Factors determining the means of suicide among suicidal patients treated by mobile emergency medical services in Brazil.
Article in BMC psychiatry, 2025. 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
objectiveTo analyse the factors associated with the means of suicide in suicidal patients treated by mobile emergency medical services (EMS) in the Botucatu and Ourinhos regions of São Paulo state, Brazil.
methodsA retrospective and comparative study was conducted to analyse 807 cases of attempted suicide treated by EMS teams from 2018 to 2019.
resultsOverall, exogenous intoxication (53%), patients aged 24 or older (64.4%), women (65.2%), and individuals who survived the occurrence (97.9%) predominated in both regions. The multiple multinomial logistic regression analysis revealed that poisoning was associated with age (OR = 1.042, 95% CI: 1.006 to 1.079; p = 0.021); suicidal ideation was associated with summer (OR = 3.001, 95% CI: 1.993 to 4.518; p < 0.001), the Botucatu region (OR = 28.143, 95% CI: 11.229 to 70.537; p < 0.001), and female sex (OR = 0.586, 95% CI: 0.385 to 0.892; p = 0.013); self-aggression was associated with the Botucatu region (OR = 5.688, 95% CI: 2.925 to 11.057; p < 0.001); and hanging was associated with female sex (OR = 0.488, 95% CI: 0.279 to 0.854; p = 0.012). Furthermore, being female (OR = 0.367, 95% CI: 0.140 to 0.961; p = 0.041), residing in the Botucatu region (OR = 0.123, 95% CI: 0.050 to 0.299; p < 0.001), and exogenous intoxication (OR = 0.014, 95% CI: 0.002 to 0.110; p < 0.001) were identified as protective factors related to the outcome of death.
conclusionRecognising multiple factors intrinsic to individual and environmental influences associated with the means of suicide used by suicidal patients treated by EMS teams highlights the importance of rapid, effective care provided by pre-hospital emergency teams for preventing deaths. The protective factors identified include being female, being from the Botucatu region, and experiencing exogenous intoxication.
