Prevalence of secondary traumatic stress in nurses: a meta-analysis of observational studies.
Synthesis in Frontiers in public health, 2026. 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
Background: The reported prevalence of secondary traumatic stress (STS) among nurses varies considerably across studies, ranging from 22. 1 to 84.4%. This meta-analysis aimed to estimate the pooled prevalence of STS and identify potential moderating factors among nurses. Methods: From the inception of each target database to April 2026, a comprehensive search was performed across PubMed, Web of Science, Scopus, Embase, Cochrane Library, CINAHL, and PsycINFO. We calculated the pooled prevalence of STS using a random-effects model and assessed heterogeneity using the I Results: A total of 28 studies comprising 7,090 nurses were included. The pooled prevalence of STS in nurses was 57.3% (95% CI: 49.7-64.9%). STS prevalence was significantly associated with mean age (β = -0.064, Conclusions: Our findings indicated that STS was very prevalent in nurses, and the prevalence is moderated by mean age, work experience, publication year, and geographic region. Regular STS assessments and multi-level support systems, such as early warning, peer support, and mental health training, are recommended to reduce STS risk and enhance the wellbeing of nurses.
