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

backgroundColorectal cancer ranks as the third most frequently diagnosed cancer globally. Adipokines, including adiponectin and leptin, are believed to play a vital role in the development and progression of tumors. This study aimed to clarify the association between circulating adiponectin and leptin concentrations and the risk of colorectal cancer and adenoma.

methodsA detailed literature review was conducted in different databases, including Google Scholar, Web of Science, Scopus, and PubMed. Articles measuring serum concentrations of adiponectin and leptin in colorectal adenoma or cancer patients were analyzed. Pooled odds ratios (ORs) and their related 95% confidence intervals (CIs) were estimated through a random-effects meta-analysis.

resultsIn total, 30 articles were analyzed. According to the meta-analysis, higher adiponectin concentrations were inversely linked to a reduced CRC risk (OR: 0.85, 95% CI: 0.74-0.96), particularly in men. However, no notable connection was detected between higher leptin concentrations and risk of CRC (OR: 1.12, 95% CI: 0.96-1.31). In subgroup analyses, BMI adjustment reinforced the negative association between higher adiponectin levels and risk of CRC, while insulin adjustment yielded non-significant results. Additionally, higher leptin levels revealed a meaningful relationship with colorectal adenoma risk (OR: 1.39, 95% CI: 1.06-1.84), whereas higher levels of adiponectin were not significantly linked to adenoma (OR: 0.79, 95% CI: 0.46-1.36).

conclusionAccording to this meta-analysis, elevated adiponectin concentrations may play a protective role against CRC, while leptin could potentially contribute to an elevated colorectal adenoma risk. Further studies are required to explore the potential mechanisms underlying adipokine-mediated colorectal carcinogenesis.
