Prehospital suicide mortality in the Lake Van basin: rural-urban disparities from three-year EMS dispatch surveillance in eastern Türkiye.
Article in BMC emergency medicine, 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
backgroundEastern Türkiye records high suicide mortality; however, prehospital emergency medical services (EMS) dispatch records from this region have not been systematically evaluated as a surveillance source. We aimed to describe EMS-attended suicide and self-harm cases in Van Province and to quantify the association between rural residence and prehospital suicide mortality.
methodsWe conducted a retrospective population-based surveillance study of all 'suicide'-coded records in the Van Province 112 EMS database (ASOS) from January 2023 to December 2025. After excluding duplicates and miscoded entries, 848 physically enacted cases formed the primary sample; 41 ideation/threat records were described separately and excluded from the primary mortality model. Prehospital death was defined as death recorded before hospital handover. Associations were estimated using multivariable logistic regression adjusted for age, sex, and method lethality, with inverse probability of treatment weighting (IPTW) as a sensitivity analysis. Daily meteorological associations were examined using Poisson regression with harmonic seasonality controls.
resultsAmong 848 physical-act cases (57.7% female; mean age 28.7 ± 12.7 years), the estimated crude annual EMS-attended rate was 25.7 per 100,000 population. Drug/chemical ingestion predominated (52.6%), whereas hanging accounted for 62.1% of prehospital deaths. The rural prehospital death rate was 24.7% compared with 10.8% in urban areas (adjusted odds ratio [aOR] 2.18, 95% CI 1.38-3.44, p < 0.001). Females constituted 33.9% of prehospital deaths (national average: 26.7%). Temperature showed a nominally significant but practically small association (incidence rate ratio [IRR] 1.006/°C, p = 0.022) that did not survive Bonferroni correction. No association with lunar phase was detected.
conclusionsIn this dispatch-based surveillance study, rural residence was associated with approximately twofold higher odds of prehospital suicide mortality even after adjustment for age, sex, and method lethality. The findings support the value of 112 dispatch data for prehospital surveillance and generate hypotheses regarding geographic access, delayed discovery, EMS resource constraints, and method lethality that require confirmation through linked dispatch-hospital data and studies with measured response intervals.
