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

aimVascular endothelial growth factor (VEGF) is linked to inflammation and angiogenesis, indicating a possible role in inflammatory bowel disease (IBD) and its main clinical manifestations, Crohn's disease (CD) and ulcerative colitis (UC). This systematic review and meta-analysis investigated studies assessing circulating VEGF concentrations in IBD patients and healthy controls, considering the effect of IBD type, sample type and geographical location.

methodsA systematic search identified 18 studies (28 group comparators) investigating 1741 IBD patients and 1291 controls. Data were extracted and analysed using standardized mean differences (SMD) with 95% confidence intervals (CI).

resultsVEGF concentrations were significantly higher in IBD patients (SMD = .71, 95% CI .38 to 1.04; p < .001). UC patients showed higher VEGF concentrations than CD patients. Serum samples indicated significant VEGF elevations, unlike plasma samples. Significant VEGF increases were observed in studies conducted in Western Europe and Asia, but not in Eastern Europe. No significant differences were found between active and inactive disease.

conclusionsVEGF concentrations are elevated in IBD patients, with variations by disease type, sample type and geography. However, VEGF is not a reliable marker of disease activity. Future research should standardize methods and explore regional influences to enhance VEGF's clinical utility as a biomarker of IBD.
