Prevalence of post-traumatic stress disorder after earthquakes among the elderly in China: A meta-analysis.
Article in World journal of emergency medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis 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
backgroundThe study aims to investigate the occurrence of post-traumatic stress disorder (PTSD) after earthquakes among the elderly.
methodsData from cross-sectional studies focusing on the prevalence of PTSD after earthquakes among the elderly were collected from PubMed, EMBASE, Cochrane Library, and China National Knowledge Infrastructure in December 2019. The search terms included post-traumatic stress disorder, earthquake, and elderly. This study used Review Manager 5.0 to evaluate the impact of the results. In addition, forest plots, sensitivity analysis, and bias analysis were carried out on the included articles. The combined estimate of the risk ratio and the standard deviation of the 95% confidence interval (95%
resultsThere were 4,834 patients included from 10 eligible studies. The sample sizes of PTSD group and non-PTSD group were 1,277 and 3,557, respectively. The meta-analysis showed that the overall occurrence of PTSD after earthquakes among the elderly was 0.25; the occurrence in females was higher than that in males, and the occurrence in the same province indicated little difference (Wenchuan city 0.25 and Ya'an city 0.24).
conclusionsAfter earthquakes, the occurrence of PTSD is higher among the elderly than among other age groups, and higher among the females than among the males, while there is little difference among different areas within the same province. This indicated that prioritized specific psychological interventions should be provided to the aged and the females.
