Association between sunshine hours and suicide attempts: Evidence from a retrospective study in Southern India.
Article in Indian journal of psychiatry, 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
Background: Suicide is a growing public health concern in India. While psychological and sociocultural factors are well studied, the role of climatic influences like sunshine duration remains underexplored. Aims: To investigate seasonal patterns in suicide attempts and assess the relationship between suicide incidence and sunshine duration in southern India. Methods: A retrospective cross-sectional study analyzed 411 suicide attempt cases from July 2017 to June 2022 at a tertiary hospital in Chennai. Demographic and clinical data were extracted, and sunshine duration was sourced from the India Meteorological Department. Results: Most attempts involved females (69%) and adults aged 19-59 (73%). Medication overdose was the leading method (46%). Attempts peaked in July, while sunshine was the highest in February-May. A strong inverse correlation was found (r = -0.81; Conclusion: Lower sunshine duration correlates with increased suicide attempts, highlighting the need to integrate environmental factors into prevention strategies.
