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

Background: Probiotic supplementation may influence mental health through the gut-brain axis, with potential effects on depression, anxiety, sleep, cognition, stress hormones, and gut microbial composition. This systematic review aimed to evaluate the effects of probiotics on psychological, physiological, and gut microbiome-related outcomes across diverse populations. Summary: A comprehensive search of PubMed, MEDLINE, PsycINFO, and ScienceDirect identified randomized controlled trials evaluating probiotic supplementation. Twenty RCTs were included, of which 15 were assessed as having a low risk of bias and five as having a high risk of bias. Commonly assessed outcomes included depression ( Key Message: Probiotic supplementation may provide beneficial effects on psychological well-being and gut microbial composition. However, heterogeneity among interventions, populations, outcome measures, and study quality warrants further well-designed RCTs.
