From prescription to practice: a qualitative study of medication non-adherence in rural Tamil Nadu, India.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo explore reasons for medication non-adherence among rural patients with diabetes and/or hypertension and to understand how health-system, personal and socio-cultural factors shape adherence behaviour.
designQualitative study using individual in-depth interviews
settingA Rural Health and Training Centre in Thiruvallur district, Tamil Nadu, India.
participants15 adults aged ≥30 years with diabetes and/or hypertension for at least 1 year were purposively recruited from the non-communicable disease clinic. Interviews were conducted in Tamil, audio-recorded, transcribed verbatim and translated into English. Two researchers independently coded the transcripts. Sample adequacy was guided by information power and concurrent assessment of code saturation.
results4 themes and 12 subthemes described health-system constraints, everyday routines and treatment beliefs, family relationships and emotional burden and experiences and strategies that reinforced medication use. Medication interruption occurred through three overlapping routes: structurally constrained interruption related to supply, affordability or access; unintentional interruption when routines were disrupted by work, travel or caregiving; and intentional modification based on perceived harm, symptoms or treatment need. Participants could move between interruption and renewed medication-taking as circumstances, emotional states and perceptions of risk changed. Family relationships could both support and hinder medication-taking, while symptoms and experienced or witnessed complications sometimes prompted re-engagement.
conclusionsMedication-taking was dynamic rather than a fixed patient characteristic. Structural, unintentional and intentional interruptions require different responses. More flexible medicine supply, structured counselling that checks understanding, attention to household influences and fasting practices and recognition of emotional strain may better support long-term medication use in rural primary care.
