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: Gut microbiota play an important role in bilirubin metabolism and may influence the course of neonatal physiological jaundice. This systematic review and meta-analysis aimed to evaluate the strain-specific efficacy of probiotics in the prevention and adjunctive treatment of neonatal physiological jaundice. Materials and Methods: A comprehensive search of PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library, World Health Organization databases, and Persian databases (Scientific information database [SID] and Magiran) for studies published up to 2024 was conducted. Randomized controlled trials (RCTs) evaluating probiotics in term and late-preterm neonates (≥35 weeks) with physiological jaundice were included. Data extraction, quality assessment, and meta-analysis were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using a random-effects model. Results: Nineteen RCTs (13 therapeutic and 6 prophylactic) were included. Prophylactic probiotic administration was associated with a reduced need for phototherapy (odds ratio [OR] =0.60; 95% confidence interval [CI]: 0.37-0.96). As an adjunct to phototherapy, probiotics were associated with lower bilirubin levels (mean difference [MD] = -1.61; 95% CI: -3.10--0.11), shorter phototherapy duration (~5 h), and reduced hospitalization (0.3 days). Reduction in bilirubin was more evident during the 2 Conclusion: Probiotics may serve as beneficial adjuncts in the prevention and management of neonatal physiological jaundice, with potential strain-dependent differences. Given heterogeneity and limited data for some strains, findings should be interpreted cautiously. Further well-designed, adequately powered RCTs are warranted.
