Prevalence of post-traumatic stress disorder in Peruvian military: a cross-sectional study.
Article in Frontiers in 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
Introduction: The COVID-19 pandemic has led us to stay at home in order to mitigate the increase in contagion, which has modified military personnel's work as they had to be on the front-line of the global fight. Post-traumatic stress disorder (PTSD) is a psychiatric condition that has become a challenge for public health. Little research has been undertaken in military population, even less in the Latin American context. The objective is determining the prevalence and factors associated with post-traumatic stress disorder in military personnel in Lambayeque, Peru. Methods: This is an analytic cross-sectional observational study in military staff that carried out first-line activities on the defense against COVID-19. The study population was comprised of 820 military personnel. To evaluate the factors associated with PTSD, we calculated prevalence ratios (PR) and confidence intervals at 95%, using simple and multiple regression models. Results: The prevalence of PTSD was 7.8% (95% CI: 5.8%-10.2%). The multiple regression model showed that smoking (PR: 2.84; 95% IC: 1.14-7.09), having worked between 13 and 18 months (PR: 2.62; 95% IC: 1.20-5.75), insomnia (PR: 4.09; 95% IC: 1.90-8.83), and fear of COVID (PR: 6.20; 95% IC: 2.70-14.22) were associated with a higher prevalence of PTSD in military personnel. Conclusion: We found that nearly one in ten military personnel presented PTSD. Factors associated with a higher prevalence included longer service time, smoking, insomnia, and fear of COVID-19. Although resilience showed a protective trend in crude analyses, this association was not significant after adjustment.
