Prevalence of Life Stressors and Posttraumatic Stress Disorder Among Women in Iceland.
Article in JAMA network open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Importance: Comprehensive data on the prevalence of various life stressors and their role in posttraumatic stress disorder (PTSD) among women are lacking. Objective: To determine the prevalence of a broad range of life stressors and their association with PTSD in a large nationally representative cohort of women. Design, Setting, and Participants: This cross-sectional analysis used data from the population-based Stress-And-Gene-Analysis, which invited women in Iceland to complete an online survey from March 1, 2018, to July 1, 2019. Participants were a nationally representative sample of women 18 to 69 years of age. This analysis was conducted from January 21, 2022, to September 13, 2024. Exposures: History of 23 life stressors assessed with the Life Events Checklist for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) and additional survey questions. Main Outcomes and Measures: The main outcome was probable PTSD during the past month assessed for the worst life stressor experienced as evaluated with the PTSD Checklist for DSM-5. Modified Poisson log-linear models were used to assess prevalence ratios (PRs) of PTSD by type of life stressor, adjusting for multiple covariates, including number of life stressors and time since the worst life stressor. Results: Overall, 28 199 women participated in the study (mean [SD] age, 43.8 [13.7] years). The prevalence of life stressors varied substantially, ranging from 3.3% for war or armed conflict-related events to 66.4% for unwanted sexual experiences. The overall prevalence of probable PTSD was 15.9% and varied substantially across life stressor types. The highest prevalence of probable PTSD was for sexual assault (1427 of 3872 [36.9%]) and lowest for natural disasters (15 of 456 [3.3%]). Interpersonal trauma, specifically sexual assault (adjusted PR [APR], 6.66 [95% CI, 4.01-11.04]), other unwanted sexual experience (APR, 4.33 [95% CI, 2.53-7.42]), and physical assault (APR, 4.44 [95% CI, 2.63-7.49]) were associated with the highest prevalence increase of probable PTSD compared with natural disasters as the reference category. Conclusions and Relevance: This cross-sectional study of 28 199 women in Iceland, which ranks highest globally in gender equality, found that sexual and physical assaults were among the most common life stressors reported and were associated with the highest prevalence of probable PTSD. The propensity of such trauma to result in PTSD calls for widespread societal efforts to prevent sexual and physical violence and reduce gender-based disparities in mental health.
