Antioxidant and anti-inflammatory effects of ginger supplementation in adults: a GRADE-assessed systematic review and dose-response meta-analysis of randomised controlled trials.

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
backgroundDisturbance of inflammatory/oxidative status of the body is an important player in chronic disease pathophysiology. Ginger (Zingiber officinale Roscoe, Zingiberaceae) supplementation has been vastly investigated in this regard. The present dose-response meta-analysis is aimed at summing up the findings of existing literature.
methodsOnline databases of PubMed, Scopus, Web of Science Core Collection, and Google Scholar were searched for eligible randomised controlled trials (RCTs) on ginger supplementation. Outcome variables included: C-reactive protein (CRP), tumour necrosis factor α (TNF-α), interleukin-6 (IL-6), total antioxidant capacity (TAC), malondialdehyde (MDA), and superoxide dismutase (SOD). Findings were reported as weighted mean differences (WMDs). Subgroup analysis was conducted. Linear and non-linear associations between dosage/duration of intervention and the observed effects were assessed. Protocol registered in PROSPERO (CRD420251011148(.
resultsTwenty-nine RCTs were included. Our findings show that ginger supplementation improves all inflammation/anti-oxidant biomarkers, as follows: CRP (WMD = -0.86 mg/L; 95% CI = - 1.10, - 0.62), TNF-α (WMD = - 1.90 pg/mL; 95% CI = - 2.61, - 1.18), IL-6 (WMD = - 1.15 pg/mL; 95% CI = - 1.90, - 0.41), TAC (WMD = 0.22 mmol/L; 95% CI = 0.06, 0.38), MDA (WMD = - 0.76 mcmol/L; 95% CI = - 1.19, - 0.33), and SOD (WMD = 48.12 u/L; 95% CI = 30.57, 65.58).
conclusionThe effect of ginger on IL-6 seems to associate with the dosage and duration of intervention in a non-linear fashion. Ginger supplementation may improve inflammatory and antioxidant biomarkers, particularly in individuals with underlying health conditions. Given the high heterogeneity among studies, findings should be interpreted cautiously.
