The effect of resveratrol supplementation on obesity indices: a critical umbrella review of interventional meta-analyses.
Synthesis in Eating and weight disorders : EWD, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveDespite several studies assessing the impact of resveratrol on obesity indices, previous meta-analyses show conflicting results. Therefore, we conducted this critical umbrella review of interventional meta-analyses on the effect of resveratrol supplementation on body mass index (BMI), body weight (BW), waist circumference (WC), and body fat.
methodsSearches were conducted across multiple databases to identify all relevant meta-analyses up to September 30th, 2025. Reported pooled effect sizes (ESs) and 95% confidence intervals (CIs) were extracted from each included study and synthesized using a random-effects model. Methodological quality was assessed using the AMSTAR 2 tool.
resultsUltimately, 18 meta-analyses were included, with results showing a small but statistically significant reduction in BW (ES: - 0.18 kg, 95% CI - 0.32 to - 0.03, p = 0.02), BMI (ES: - 0.14 kg/m
conclusionOur review confirms that resveratrol supplementation reduces BW, BMI, WC, and body fat, particularly on doses > 400 mg/day and interventions lasting ˃12 weeks, with small effect sizes. Based on our findings, resveratrol supplementation could be considered as a complementary therapy in the management of obesity.
