1 · What the graph read from it

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.

2 · The registry

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

backgroundProbiotics can modulate the microbiota and decrease uric acid levels.

objectivesThis meta-analysis aimed to assess the effects of probiotics on uric acid levels.

methodsThe keywords "probiotics", "uric acid", "gout", "hyperuricemia" were searched in PubMed Medline, EMBASE, Web of Science, and Google Scholar. The search was limited to the English, French, Italian, and Spanish languages, and to the period between 1 January 2000 to 30 August 2024. We included RCTs and observational studies comparing probiotics to placebo. We excluded studies reporting (1) prebiotics, symbiotics, or postbiotics, (2) animal studies, and (3) case reports, commentaries, or reviews. Two independent reviewers performed quality assessment and data extraction. This meta-analysis was performed according to the PRISMA 2020 and AMSTAR 2 guidelines. The main outcome measure was uric acid levels "after-before" probiotic versus placebo interventions. Forest plots summarized the data using a random model.

resultsNine studies included 394 patients, of whom 201 were treated with probiotics and 193 with placebo. There was a statistically significant difference in favor of the probiotic group compared with the control group regarding the main outcome measure. However, substantial heterogeneity was noted, explained (after applying subgroup analysis and meta-regression) by the following moderators: continent, diseased/healthy, male sex, and monostrain probiotics.

conclusionsThis meta-analysis demonstrates that probiotics reduced uric acid levels in Asian males who had disease and were treated with monostrain probiotics.
