This post explains how AI-enabled qualitative research can make the findings from a PLOS One qualitative study actionable for researchers, NGOs, and WASH program teams. The primary keyword "qualitative analysis of menstrual health" guides practical steps: from extracting themes and quotes to quantifying patterns across participant segments. According to PLOS One (published July 24, 2026), the Khulna Railway Slum study recorded 18 in-depth interviews and 5 key informant interviews between 01/09/2025 and 31/10/2025, producing rich, policy-relevant themes about water, sanitation, disposal, stigma, and gendered access to products.
Key Takeaways
According to PLOS One (published July 24, 2026), women and adolescent girls in Khulna’s Railway Slum experience menstruation as a socially and structurally shaped burden driven by inadequate WASH, stigma, and economic constraints.
- PLOS One (24 July 2026) reports 18 in-depth interviews and 5 key informant interviews collected between 01/09/2025 and 31/10/2025.
- PLOS One (24 July 2026) finds three dominant domains shaping experience: structural-environmental constraints, socio-cultural stigma, and gendered inequities in access to menstrual resources.
- PLOS One (24 July 2026) reports that 72% of participants had lived in the slum for over eight years, amplifying chronic exposure to poor sanitation and limited water.
- Direct quotations from participants illuminate mechanisms: "When water stops coming from the tap, I wait for hours. If it doesn’t come, I can’t clean myself properly" (IDI-08, PLOS One).
What Happened: study design and measurements
Answer: the PLOS One study used in-depth qualitative methods to map lived menstrual experiences in one Khulna informal settlement and to surface actionable themes.
According to PLOS One (published July 24, 2026), researchers conducted 18 IDIs with women and adolescent girls aged 15–45 and 5 KIIs with community health workers and NGO staff between 01/09/2025 and 31/10/2025.
According to PLOS One, data collection used semi-structured interviews in Bengali, audio recordings, and thematic analysis with a combined deductive-inductive codebook guided by Feminist Political Ecology; NVivo v12 supported coding.
According to PLOS One, ethical approval was granted by Gopalganj Science and Technology University IRB (Approval No. 473478-FY 2024–2025; Approval Date: 10 August 2025).
Findings snapshot

| 01/09/2025–31/10/2025, PLOS One | In-depth interviews | 18 participants aged 15–45 | Rich firsthand narratives suitable for thematic and quote extraction |
| 01/09/2025–31/10/2025, PLOS One | Key informant interviews | 5 stakeholders | Triangulation with NGO and school perspectives |
| 24/07/2026, PLOS One | Dominant themes | 3 domains: WASH constraints, stigma, gendered inequity | Interventions must combine infrastructure, education, and economic access |
| 24/07/2026, PLOS One | Residency duration | 72% lived in the slum >8 years | Long-term exposure indicates structural, not episodic, problems |
Implications for researchers and program teams
How should qualitative researchers prioritize analysis?
Answer: prioritize cross-cutting codes that link environment, stigma, and resource access to identify leverage points for intervention.
According to PLOS One (published July 24, 2026), the three conceptual domains can be mapped to program levers: WASH upgrades, community education, and subsidized product distribution.
Researchers should extract verbatim quotes tied to each domain (for example, "The toilet near our room has no door. Boys and men walk by all the time. I feel scared to change my clothes there" (IDI-04)) to illustrate lived mechanisms in reports and grant proposals.
What should NGOs and WASH teams change in monitoring?
Answer: monitor menstrual dignity indicators alongside standard WASH metrics, and collect disaggregated qualitative feedback monthly.
According to PLOS One, women reported lack of privacy, water scarcity, and unsafe disposal practices; programs should add indicators for privacy (locks, lighting), continuous water availability, and menstrual waste options.
Programs can triangulate short IDI extracts with routine service metrics to detect seasonal or acute failures (the PLOS One sample collected data before the 2026 monsoon vulnerabilities were explicitly discussed).
How Evidano helps: AI mappings from problem to feature
Problem: dispersed qualitative data slows synthesis → Solution: thematic synthesis at scale
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
According to the PLOS One methods (24 July 2026), manual coding used NVivo v12 and independent coders to reach consensus; Evidano accelerates the same steps by ingesting transcripts and producing reproducible thematic maps with source-linked quotations.
Feature mapping: upload transcripts, run automated thematic extraction, confirm and refine codes, and export a codebook and frequency tables for donor reports.
Problem: finding representative quotes is time-consuming → Solution: quote search and tagging
Answer: Evidano can surface participant quotes tied to codes and segments so teams can quote ethically and quickly.
According to PLOS One, participant quotes such as "When water stops coming from the tap, I wait for hours" (IDI-08) are central evidence; Evidano can index quotes by code, participant profile, and date to create shareable evidence packets.
Relevant Evidano features: transcription with PII redaction, code→subcode hierarchy, and exportable quote banks documented for ethics.
Problem: multilingual or audio data increases overhead → Solution: transcription and translation
Answer: use integrated speech-to-text and translation to convert Bengali audio into coded English transcripts ready for cross-study comparison.
According to PLOS One, interviews were conducted in Bengali and then translated; Evidano’s speech-to-text and translation tools can standardize that process while preserving custom dictionaries and consent notes.
Feature mapping: audio ingestion → automated transcript → human review → AI-assisted coding saves weeks on multi-language projects.
Problem: data security and ethical limits on sharing → Solution: privacy-first workflows
Answer: Evidano supports encrypted storage and controlled access so teams can analyze sensitive menstrual data while preserving participant confidentiality.
Evidano keeps data encrypted and does not use customer data to train third-party models, which supports the IRB restrictions reported by the PLOS One team (Gopalganj Science and Technology University IRB, Approval Date: 10 August 2025).
Teams can produce de-identified thematic outputs and export minimal datasets (quote banks, codebook, frequency tables) for ethical sharing in line with the source study.

FAQ: qualitative analysis of menstrual health
How many interviews are enough for a thematic study like the PLOS One Khulna paper?
Answer: aim for saturation rather than a fixed number; the PLOS One study reached saturation at 18 IDIs and 5 KIIs.
According to PLOS One (data collected 01/09/2025–31/10/2025), the research team stopped at 18 IDIs because no new conceptual codes emerged after the fifteenth interview and three additional interviews confirmed saturation.
Can AI tools preserve ethical constraints on sensitive menstrual transcripts?
Answer: yes, if the platform supports PII redaction, encrypted storage, and access controls.
According to the PLOS One ethics statement (IRB Approval Date: 10 August 2025), full transcripts were withheld for confidentiality; AI workflows should mirror that practice by producing de-identified outputs and controlled minimal datasets for sharing.
What immediate indicators should programs add to monitoring after reading PLOS One?
Answer: add menstrual dignity indicators for privacy, continuous water availability, and disposal options.
According to PLOS One, lack of locks, intermittent water, and no disposal bins were repeatedly cited; track these monthly alongside qualitative feedback to catch recurring barriers.
How do you convert qualitative themes into quantifiable program metrics?
Answer: code frequency, segment by age/marital status, and convert occurrence rates into dashboard indicators.
According to PLOS One, participants were stratified by age and residency duration; use those segments to count mentions of specific barriers and present them as percentages in reports.
Conclusion & Next Steps
Answer: AI-enabled qualitative analysis turns the PLOS One Khulna study from narrative evidence into targeted program actions on WASH, education, and product access.
According to PLOS One (published July 24, 2026), the study’s themes directly map to practical interventions that NGOs and municipal actors can implement and monitor.
Next steps for research teams: ingest transcripts and KIIs, run thematic extraction, validate codes with local stakeholders, and produce a minimal de-identified dataset for policymakers.
