Effect of zinc supplementation on diarrhoea in HIV infection: a protocol for systematic review and meta-analysis of controlled clinical trials.
Article in BMJ open, 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
introductionDiarrhoea is a common problem in people living with HIV. Some trials have demonstrated the effectiveness of zinc supplementation in the prevention and treatment of diarrhoea; however, several studies employing the effectiveness of zinc supplementation for reducing diarrhoea in HIV infection have reported heterogeneous outcomes, necessitating a systematic review to provide an exhaustive summary of current evidence. This review aims to pool the available evidence on the effectiveness of zinc supplementation on diarrhoea in HIV infection. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. A systematic literature search will be conducted in Chinese and English databases, including PubMed, Scopus, Google Scholar, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure, Chinese Scientific Journal Database, SinoMed and Wanfang, as part of our search strategy from inception to 17 May 2025. Two reviewers will independently identify eligible studies and extract data. The risk of bias in included studies will be assessed using version 2 of the Cochrane risk-of-bias tool for randomised trials. The risk ratio and 95% CIs will be used to estimate the efficacy of treatment and evaluation approach to rate the certainty of evidence. Cochran's Q and the I ETHICS AND DISSEMINATION: Because no patients were involved, ethical approval was not required. The final results of this research will be submitted to a peer-reviewed journal or presented at relevant conferences, and any deviations from this protocol will be recorded and explained in the final report. PROSPERO REGISTRATION NUMBER: CRD42022328098.
