Sex-specific differences in survival after out-of-hospital cardiac arrest: a nationwide, population-based observational study.
Observational study in Critical care (London, England), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers, 2 of them syntheses that pooled 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.
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
backgroundIt remains unclear whether men have more favorable survival outcomes after out-of-hospital cardiac arrest (OHCA) than women.
methodsWe reviewed a total of 386,535 patients aged ≥ 18 years with OHCA who were included in the Japanese registry from 2013 to 2016. The study endpoints were the rates of 1-month survival and neurologically intact survival (Cerebral Performance Category Scale score = 1 or 2). Based on age, the reviewed patients were categorized into the following eight groups: < 30, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89, and ≥ 90 years. The survival outcomes in men and women were compared using hierarchical propensity score matching.
resultsThe crude survival rate was significantly higher in men than in women in five groups: 30-39, 40-49, 50-59, 60-69, and 70-79 years (all P < 0.001). Similarly, the crude neurologically intact survival rate was significantly higher in men than in women in seven groups: < 30, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89 years (all P < 0.005). However, multivariate logistic regression analysis of each group revealed no significant sex-specific differences in 1-month survival outcomes (all P > 0.02). Moreover, after hierarchical propensity score matching, the survival outcomes did not significantly differ between both sexes (all P > 0.05).
conclusionsNo significant sex-specific differences were found in the rates of 1-month survival and neurologically intact survival after OHCA.
