1 · What the graph read from it

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.

2 · The registry

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

backgroundWomen have been observed to have a higher risk of developing posttraumatic stress symptoms (PTSS) after disaster compared to men. In a study of survivors of an earthquake, we sought to investigate: whether there was differential exposure to disaster-related trauma by gender; whether women and men have differential vulnerability to trauma; and what factors could explain the gender difference in PTSS.

methodsData from a cohort of community-dwelling older survivors of the 2011 Great East Japan Earthquake and Tsunami was used. Data were obtained before (2010) and 2.5-years after the disaster (n = 3,334).

resultsWomen suffered 1.6 times higher prevalence of PTSS than men (31.0% vs. 19.4%). Women were more likely to experience loss of relatives (29.2% vs. 23.2%), while men were more likely to report loss of friends (17.1% vs. 14.5%) and separation from work (7.5% vs. 4.6%). We did not find evidence for differential vulnerability to disaster-related trauma. Indeed, the gender gap in PTSS was larger among individuals who did not experience trauma. Women experienced greater deterioration of non-kin instrumental support, which significantly mediated the association between gender and PTSS. LIMITATIONS: We have no information on PTSS prior to the earthquake. Nor do we have clinician diagnoses of PTSD.

conclusionsWomen experienced housing damages and loss of relatives more often than men, which explained ∼21% of the gender gap in PTSS after disaster. Women reported more non-kin support prior to the disaster, but they also experienced greater deterioration of it, which explained ∼21% of the gender gap.
