The effect of berberine on obesity indices: a systematic review and meta-analysis.
Synthesis in International journal of obesity (2005), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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 AND
aimObesity is an already identified risk factor for various noncommunicable diseases. Berberine is an alkaloid that has manifested a significant effect in the treatment of obesity and its complications. The aim of this systematic review and meta analysis is to evaluate the effect of berberine on obesity indices.
methodsWe conducted a comprehensive search of Scopus, PubMed, Web of Science, and Google Scholar for randomized controlled trials (RCTs) investigating berberine's impact on obesity indices in adults. Eligible studies included human trials with quantitative outcomes for weight, BMI, WC, or WHR. Animal studies, reviews, and non-RCTs were excluded. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Cochrane RoB 2 tool. A random-effects meta-analysis was performed to calculate mean differences (MDs) and 95% confidence intervals (CIs). Heterogeneity was evaluated using I² statistics.
resultsA total of 23 articles were included. Berberine significantly reduced body weight (MD of -0.88 kg, 95% CI: -1.36 to -0.39, p = 0.0003), BMI (MD of -0.48 kg/m², 95% CI: -0.89 to -0.07, p < 0.0216), and WC (MD of -1.32 kg/m², 95% CI: -2.24 to -0.41, p < 0.0046). However, berberine did not significantly reduce WHR compared to control groups (MD of -0.01, 95% CI: -0.03 to 0.01). Meta-regression revealed no association between berberine use and age.
conclusionBerberine use significantly reduces body weight, BMI, and WC but does not significantly reduce WHR. Future trials should focus on improving reporting standards for biochemical characterization (such as purity, potency and gram amounts) and address common biases such as lack of blinding and randomization to enhance the reliability of the evidence.
