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

purposeThe main aim of this study was to compare the efficacy and safety of different biliary drainage strategies, including percutaneous transhepatic biliary drainage (PTBD) versus endoscopic biliary stenting (EBS) and unilateral versus bilateral stenting, in patients with unresectable malignant hilar biliary strictures (MHBSs). PATIENTS AND

methodsThis was a retrospective review of patients with inoperable MHBSs who underwent biliary drainage by either EBS or PTBD. Efficacy and safety were compared between the two pathways and between unilateral and bilateral stenting in the EBS group. The survival duration was analyzed with K-M curves and Log rank tests.

resultsFrom January 2015 to December 2019, a total of 206 (126: EBS and 80: PTBD) patients with MHBSs were enrolled in our study and underwent 270 procedures (173: EBS and 97: PTBD). Bilateral stenting was superior to unilateral stenting in terms of clinical success (69.6% vs 50.6%, p=0.039), especially for patients with Bismuth type IV (70.0% vs 30.3%, p=0.002). A higher decrease in bilirubin was seen with PTBD in patients with Bismuth types III-IV (66.9 vs 36.7, p=0.006). A survival advantage was seen in successful drainage (227 days vs 82 days, p<0.001), lower tumor-node-metastasis (TNM) scores (I-II) (195 days vs 139 days, p=0.012), and cholangiocarcinoma (184 days vs 84 days, p=0.001).

conclusionFor patients with advanced MHBSs, bilateral stenting may achieve a better drainage effect than unilateral stenting, and PTBD may have a better performance in relieving cholestasis than EBS. Successful drainage and cholangiocarcinoma may provide greater long-term survival benefits.
