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
objectiveTo describe the toxicology of suicide cases recorded in the state of Rio Grande do Sul, Brazil, from 2017 to 2019.
methodThe present descriptive, cross-sectional study examined all the medico-legal reports and police records related to suicide deaths in the state. Multiple correspondence analyses were performed along with independent logistic regression models having ethanol, anxiolytic and antidepressant drugs, illicit drugs, and non-medical substances as dependent variables.
resultsEthanol was investigated in 2 978 samples, with positive results in 28.5%. The odds of a positive ethanol finding were 0.5 time higher (95%CI: 1.1; 2.2) for suicides occurring at night, 1.0 (95%CI: 1.4; 2.9) time higher for suicides occurring on weekends, and 0.9 (95%CI: 1.3; 2.7) time higher in individuals with a prior criminal record. Investigation of psychotropic drugs (2 900 samples) was positive in 30.4% samples. Anxiolytics were the most common medication detected, with 1.5 (95%CI: 1.6; 4.1) time higher odds of occurrence in women and 0.8 time higher odds (95%CI: 1.2; 2.7) for suicides occurring in the fall-winter. The odds of detecting illicit drugs (n = 338) were 4.1 times higher (95%CI: 1.9; 14.4) in the regions of Pelotas (south of the state) vs. Passo Fundo (north), and 1.2 (95%CI: 1.3; 3.6) time higher in cases with positive ethanol results, without significant difference between adolescents and adults.
conclusionsDespite the lack of evidence on causality, the present results support a link between suicide and several psychoactive drugs. Medico-legal experts should be guided regarding the need to perform toxicological tests in all suicide cases.
