1 · What the graph read from 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.

2 · The registry

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

backgroundCurcumin, the main bioactive compound in Curcuma longa L., has long been traditionally used for the treatment of upper gastrointestinal diseases. Preclinical studies have provided substantial evidence supporting its potential therapeutic effects. However, a systematic synthesis of these findings is lacking. This study aimed to evaluate the effects of curcumin on upper gastrointestinal outcomes in animals through systematic review and meta-analysis.

methodsStudies were retrieved from three databases (PubMed, Scopus, and Embase) and through a hand search in Google Scholar, covering the period from inception to 2024. Animal studies comparing curcumin with control were selected and analyzed using RStudio version 2024.12.0. A random-effects model was applied to estimate the main effect sizes. The risk of bias was assessed using the SYRCLE’s tool. Subgroup analysis, meta-regression, and qualitative synthesis were also performed.

resultsA total of 49 studies were included in the analysis. The results indicated that curcumin significantly improved various outcomes, such as acid output (SMD = -1.47; 95% CI: -2.03–-0.92; p < 0.0001) and ulcer index (SMD = -2.19; 95% CI: -2.64–-1.73; p < 0.0001) in animals. It also improved oxidative stress, inflammatory markers, blood glucose level, and gastric emptying rate. However, the analyses revealed substantial heterogeneity, and the risk of bias was unclear in most studies, with five studies assessed as having a high risk of bias.

conclusionsCurcumin exhibits beneficial effects on various upper gastrointestinal disorders in animal models, including gastric ulcers, diabetic gastroparesis, esophageal diseases, Helicobacter pylori infection, and gastritis. These findings underscore curcumin’s therapeutic potential and highlight the need for clinical investigations to validate its translational applicability in humans.
