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

backgroundMalignant biliary obstruction is a challenging problem for cancer patients. Here we evaluate predictive factors for survival following percutaneous drainage for malignant biliary obstruction in patients in whom endoscopic drainage was unsuccessful or insufficient.

methodsA retrospective register study in a tertiary-level university hospital.

resultsA total of 643 cancer patients (317 females and 326 males) with malignant biliary obstruction were treated with percutaneous drainage at our hospital between 1999 and 2016. Their median overall survival rate was 2.6 months, with a 95% confidence interval (CI) of 2.2-3.0. Independent factors predicting poor outcome were metastatic cancer, with a hazard ratio (HR) of 2.2 (95% CI 1.8-2.7); Eastern Cooperative Oncology Group performance status (ECOG PS) of 2 (HR 2.3; 95% CI 1.8-2.8); ECOG PS of 3-4 (HR 3.5; 95% CI 2.8-4.4), American Society of Anesthesiologists physical status classification (ASA) of 4 (HR 2.1; 95% CI 1.5-2.9); and bilirubin of ≥60.0 µmol/L within 30 days post-drainage (HR 1.3; 95% CI 1.1-1.6). During the time periods 1999-2004 and 2005-2010, patients had poorer outcomes (HR 1.4; 95% CI 1.1-1.7 and HR 1.4; 95% CI 1.2-1.8) than during the last period 2011-2016.

conclusionPatients with cancer who underwent percutaneous biliary drainage for biliary obstruction had a poor median overall survival. The usefulness of biliary drainage, especially in patients with metastatic cancer, poor ECOG PS, and high ASA class, should be critically considered.
