Estimating the total prevalence of PTSD among the UK police force: Formal comment on Stevelink et al. (2020).
Article in PloS one, 2022. 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
Two recent surveys have reported widely differing prevalence rates for posttraumatic stress disorder (PTSD) within the U.K. police force. Stevelink et al. (2020) reported a rate of 3.9% whereas a survey conducted for the charity Police Care UK reported a rate of 20.6%. In this comment we discuss how definitions and methodological factors can impact prevalence rates. We consider a number of possible reasons for the discrepancy between the surveys, and conclude that it is most likely a method artefact. Stevelink et al.'s survey reported the prevalence of recent-onset DSM-IV PTSD only, whereas the Police Care UK survey reported the total ICD-11 PTSD and Complex PTSD prevalence, regardless of when in the person's career the traumatic events occurred. Analysing the Police Care UK data using Stevelink et al.'s procedures produced practically identical prevalence rates, suggesting that the discrepancy was apparent rather than real.
