Risk Factors for Posttraumatic Stress Disorder in Mexican Psychiatric Trauma Survivors.
Observational study in Actas espanolas de psiquiatria, 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
backgroundThere is extensive evidence linking specific sociodemographic and clinical factors to increased vulnerability for Posttraumatic Stress Disorder (PTSD). However, most studies have focused on community samples, and little is known about how such factors shape PTSD risk in clinical psychiatric settings in Latin America, where trauma exposure is highly prevalent. The present study addresses these gaps by examining sociodemographic characteristics and specific types of traumatic events linked to PTSD diagnosis among individuals receiving care at a tertiary mental health facility in Mexico City, Mexico.
methodsA cross-sectional, observational design was employed, enrolling 160 psychiatric patients. Participants were assessed for exposure to potentially traumatic events using the Life Events Checklist for DSM-5 (LEC-5). Probable PTSD was initially identified with the PTSD Checklist for DSM-5 (PCL-5), followed by diagnostic confirmation using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). Sociodemographic data, including age, sex, and educational attainment, were also collected. Multivariate logistic regression was used to identify PTSD predictors, with a significance set at
resultsThe frequency of PTSD in the sample was 31.9%. Multivariate logistic regression analysis revealed that sexual aggression was the strongest independent predictor of PTSD (odds ratio (OR) = 38.49; 95% confidence interval (CI): 10.59-139.95;
conclusionsSexual aggression, female sex, and older age were significantly associated with a PTSD diagnosis among psychiatric trauma survivors. These findings underscore the importance of incorporating trauma-informed care principles and systematic screening for sexual violence into mental health settings to improve diagnostic accuracy and optimize interventions for this population.
