Proton pump inhibitor use and risk of depression among Sudanese adults: a cross-sectional community-based study.
Article in Frontiers in psychiatry, 2025. 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: Depression is a major global public health issue. There is little available data regarding the association between the use of proton pump inhibitors (PPIs) and depression. The current study aimed to investigate the association between PPIs and depression among adults in Central Sudan. Methods: A community-based cross-sectional study was conducted to examine adults in Central Sudan. Sociodemographic data and medical history were collected. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Multivariate binary regression analyses, modified Poisson regression analyses, and propensity score matching (PSM) were performed. Results: We enrolled 914 adults (317 [34.7%] men and 597 [65.3%] women). Participants' median (interquartile range) age was 38.0 (27.0-52.0) years. Of the participants, 255 (27.9%) had used PPIs. In Poisson regression, after adjusting for confounders (age, sex, education, occupation, marital status, hypertension, diabetes mellitus, body mass index, smoking, alcohol), use of PPIs [adjusted relative risk = 1.30, 95% confidence interval (CI) = 1.21-1.40] was associated with a higher depression score. Of 914 adults, 155 (17.0%) had depression (PHQ-9 score of ≥ 8). Before matching (PSM), in multivariate binary regression (after removing confounders), PPIs were associated with depression [adjusted odds ratio (AOR)= 1.64; 95% CI = 1.14-2.37]. After matching, PPIs were associated with depression (AOR = 1.66; 95% CI = 1.13-2.41). Conclusion: This study revealed a positive association between PPI use and depression. Longitudinal studies will be necessary to examine this relationship in more depth.
