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

Objective: Menopause leads to hormonal changes that increase visceral fat, raising risks for metabolic disorders and breast cancer due to altered adipocytokine levels. Green tea ( Materials and Methods: This study reviewed randomized controlled trials (RCTs) from PubMed, Science Direct, Cochrane Library, and Google Scholar up to March 2024, focusing on green tea's effects on leptin, adiponectin, ghrelin, and insulin. Eight RCTs with 632 participants were analyzed using standardized mean differences (SMDs) with 95% confidence intervals (CIs) in a random-effects model. Heterogeneity was measured with the I Results: Green tea significantly reduced ghrelin levels (SMD: -4.63, 95% CI: -8.44 to -0.82, p = 0.02, I Conclusion: Green tea notably reduced ghrelin, with context-specific effects on leptin, adiponectin, and insulin based on dose, duration, and body mass index (BMI), suggesting tailored benefits for postmenopausal women's metabolic health.
