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

backgroundEndoscopic treatment is recommended for the management of esophageal varices. However, variceal recurrence or rebleeding is common after endoscopic variceal eradication. Our study aimed to systematically evaluate the prevalence of esophageal collateral veins (ECVs) and the association of ECVs with recurrence of esophageal varices or rebleeding from esophageal varices after endoscopic treatment.

methodsWe searched the relevant literature through the PubMed, EMBASE, and Cochrane Library databases. Prevalence of paraesophageal veins (para-EVs), periesophageal veins (peri-EVs), and perforating veins (PVs) were pooled. Risk ratio (RR) and odds ratio (OR) with 95% confidence intervals (CIs) were calculated for cohort studies and case-control studies, respectively. A random-effects model was employed. Heterogeneity among studies was calculated.

resultsAmong the 532 retrieved papers, 28 were included. The pooled prevalence of para-EVs, peri-EVs, and PVs in patients with esophageal varices was 73%, 88%, and 54%, respectively. The pooled prevalence of para-EVs and PVs in patients with recurrence of esophageal varices was 87% and 62%, respectively. The risk for recurrence of esophageal varices was significantly increased in patients with PVs (OR

conclusionsECVs are common in patients with esophageal varices. Identification of ECVs could be helpful for predicting the recurrence of esophageal varices or rebleeding from esophageal varices after endoscopic treatment.
