Effects of ginger intervention on anthropometric and body composition indices in patients with type 2 diabetes: a GRADE-assessed systematic review and meta-analysis of randomized controlled trials.
Synthesis in BMC complementary medicine and therapies, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsEvidence on the effects of ginger supplementation on anthropometric and body composition indices in adults with type 2 diabetes mellitus (T2DM) is inconsistent, and the certainty of this evidence has not been fully evaluated. This study aimed to systematically review and meta-analyze randomized controlled trials assessing these effects.
methodsPubMed, Scopus, and Web of Science were searched until October 5, 2025. We used random-effects meta-analysis to find average differences with 95% CIs. Study quality and evidence certainty were checked with Cochrane RoB-2 tool and GRADE approach. Subgroup, meta-regression, sensitivity, and publication bias analyses were also done.
resultsThis meta-analysis included 692 participants from 12 RCTs. Ginger supplementation significantly reduced body mass index (BMI) (- 0.24 kg/m²; 95% CI: -0.48, - 0.00; p = 0.043) and body fat percentage (BF%) (- 1.44%; 95% CI: -2.49, - 0.38; p = 0.007), while no significant effects were observed on body weight (BW), waist circumference (WC), hip circumference (HC), or waist-to-hip ratio (WHR). Bias assessment showed 9 studies with some concerns, 1 low, and 2 high risk. Evidence quality was moderate for 4 outcomes (BMI, WHR, HC, BF%), low for WC, and high for BW.
conclusionGinger reduced BMI and BF%, with no significant change in BW, WHR, HC, or WC.
trial registrationThis study was prospectively registered in PROSPERO (CRD420251162956).
