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

backgroundCurrent guidelines have limited consensus on the approach to portal venous thrombosis (PVT) in cirrhotic patients. While there is rising interest in direct oral anticoagulants (DOACs) use for PVT, current evidence is limited by small sample size and lack of comparisons to traditional anticoagulants. Thus, a network meta-analysis was conducted to compare the use of DOACs with traditional anticoagulants.

methodsMedline and Embase were searched for articles about anticoagulation use in cirrhotic patients with nontumorous PVT for articles on DOACs, warfarin, low-molecular weight heparin (LMWH) or antithrombin III. A network analysis was conducted using risk ratios (RR) with surface under the cumulative ranking curve (SUCRA). A single-arm meta-analysis was used to summarize the outcomes of DOAC treatment.

resultsA total of 10 articles were included in the study. 79.5% (CI 38.8-95.9) of DOACs patients achieved complete or partial recanalization and 9.80% (CI 4.50-20.0) experienced a bleeding event. DOACs were superior to LMWH (RR 2.299, CI 1.037-5.093, p = 0.040), warfarin (RR 1.762, CI 1.017-3.053, p = 0.043) and no treatment (RR 3.489, CI 1.394-8.733, p = 0.008) in complete recanalization. For partial recanalization, while DOACs were not superior to any treatment, they had the highest probability in achieving partial recanalization in SUCRA analysis. Bleeding risk and mortality were similar compared to other treatments.

conclusionThe network analysis supports the use of DOACs in cirrhotic patients, with significant rates of complete recanalization compared to other treatments without increasing bleeding risk. DOACs can potentially be considered for nontumorous PVT in cirrhosis.
