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

backgroundIn the era of bare stents, transjugular intrahepatic portosystemic shunt (TIPS) is the second-line choice of therapy for the prevention of variceal rebleeding in liver cirrhosis. In the era of covered stents, the role of TIPS should be re-evaluated.

aimThe aim of the study was to compare the outcomes of covered TIPS versus the traditional first-line therapy (i.e, drug plus endoscopic therapy) for the prevention of variceal rebleeding in liver cirrhosis.

methodsAll relevant randomized controlled trials were searched via the PubMed, EMBASE, and Cochrane Library databases. Hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) and P values were calculated for the cumulative risk and overall risk, respectively. Heterogeneity among studies was also calculated.

resultsThree of 111 retrieved papers were eligible. Among them, the proportion of patients who were switched from drug plus endoscopic therapy to TIPS was 16% to 25%. The risk of bias was relatively low in all included randomized controlled trials. Meta-analyses demonstrated that the covered TIPS group had a similar overall survival (HR = 0.84, 95% CI = 0.55-1.28, P = 0.41; OR = 1.00, 95% CI = 0.59-1.69, P = 0.99), a significantly lower risk of variceal rebleeding (HR = 0.30, 95% CI = 0.18-0.48, P < 0.00001; OR = 0.24, 95% CI = 0.12-0.46, P < 0.0001), and a similar risk of hepatic encephalopathy (HR = 1.35, 95% CI = 0.72-2.53, P = 0.36; OR = 1.28, 95% CI = 0.54-3.04, P = 0.57). In most of meta-analyses, the heterogeneity among studies was not statistically significant.

conclusionsCompared with drug plus endoscopic therapy, covered TIPS had a significant benefit of preventing from variceal rebleeding, but did not increase the overall survival or risk of hepatic encephalopathy.
