Impact of alcohol use, combat exposure, and posttraumatic stress on verbal and visual working memory performance in post-9/11 veterans.
Article in Psychological trauma : theory, research, practice and policy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivePosttraumatic stress disorder (PTSD) and alcohol use (AU) are highly prevalent and comorbid among post-9/11 U.S. military veterans. Both issues are associated with working memory (WM) deficits, but have rarely been studied concurrently in cognitive studies of post-9/11 veterans. They also have been measured inconsistently, with variable outcomes, in prior veteran studies despite their relevance to new intervention paradigms involving WM.
methodThe present study evaluated 52 post-9/11 veterans [predominantly male (94.2%); White (44.2%) or Black (36.5%); 50% being diagnosed with PTSD based on CAPS-5 results] with objectively verified valid neuropsychological test performance on measures of PTSD, AU, combat exposure, and verbal and visual WM.
resultsPTSD was not associated with verbal or visual WM performances, whereas AU and combat exposure were significantly associated with poorer visual WM performances.
conclusionsAU and prior combat exposure may influence visual WM performances in post-9/11 veterans, which is relevant to novel PTSD treatment paradigms. This sample was limited to mostly male and White or Black participants, and future studies should focus on sampling more heterogeneous groups of veterans with regard to sex and ethnicity. Improvements in specification/multimodal WM assessment are important for future research, as these may directly impact developing intervention efforts.
