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

BACKGROUND AND

aimEndoscopic biliary drainage with placement of a self-expanding metal stent (SEMS) is the preferred palliative treatment of malignant biliary obstruction. Recent advances in the treatment have prolonged survival, thus, increasing the chance of recurrent biliary obstruction (RBO) after SEMS placement. The aim of this study was to compare different endoscopic approaches in patients with a SEMS and RBO, regarding clinical success and time to RBO.

methodsThis retrospective study included all patients with a SEMS placed because of malignant biliary strictures who underwent endoscopic retrograde cholangiopancreatography between January 2011 and December 2018. We evaluated the results of different endoscopic interventions to RBO, including insertion of a new SEMS, stent cleaning, and insertion of a plastic stent (PS).

resultsFrom January 2011 to December 2018, 70 (22.4%) patients developed RBO requiring endoscopic reintervention (n = 105 sessions). From the 105 ERCPs, technical success, clinical success, and adverse events rates were 91,4%, 71,8%, and 7,8%, respectively. Younger age (OR = 1.11 95%CI: 1.03-1.19) and the finding of a patent SEMS (OR = 0.17 95%CI: 0.04-0.08) were predictors of clinical failure (P = 0.006 and P = 0.024, respectively). The mean patency time (in days) after endoscopic reintervention was greater for SEMSs than for PSs (417.2 [95% CI: 250.0-584.4] vs 175.2 [95% CI: 124.0-226.5], P = 0.002).

conclusionsCorrect identification and treatment of the causal factor of RBO typically lead to technical and clinical success. Placement of a second SEMS provides longer patency compared to a plastic stent if ingrowth (overgrowth) occurs.
