The effect of seasonal and meteorological factors on suicide rates in the Lithuanian population in 2001-2021: a case‑crossover study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe creation and implementation of suicide prevention measures requires an evaluation of the full range of potential risk factors. This study examined the associations between the total number of suicides in the season-specific context and various meteorological parameters in Lithuania as a country of the Boreal region.
methodsThis study included data on 21,487 cases of suicide in Lithuania from 2001 to 2021. The data were collected from the Register of the Institute of Hygiene. The associations between weather variables and the daily number of suicides were evaluated using a multivariate Poisson regression.
resultsThe rate ratio (RR) of suicide was observed to be highest in two summer months, June and July (1.35 and 1.36, respectively), compared to January, with the same tendency in both sexes and different ages. Elevated temperature was associated with a significantly higher RR of suicide in the general population, in men, and across all ages. Moreover, a higher number of sunny hours per day was also associated with higher RR in the whole sample, in both sexes and at the youngest and the oldest ages. Higher atmospheric pressure was found to be associated with lower suicide RR in the total sample, in men, and in the youngest and the middle age groups. An average relative humidity (RH) of 50% or more, compared to an average relative humidity < 50%, was associated with a significantly higher RR of suicide in the total sample and in the men's group.
conclusionsThere is significant evidence of seasonal effects on suicide. Clinical services in Lithuania should be aware of the risk of suicide on the hot, long summer days, especially among men.
