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

backgroundPlastic stent placement is required when biliary stones cannot be completely removed during the initial endoscopic retrograde cholangiopancreatography (ERCP). Although double half-pigtail plastic stents (DHPs) help prevent stent migration, their clinical utility has not yet been evaluated.

methodsWe retrospectively reviewed data from 221 patients who underwent DHP placement for acute calculous cholangitis (ACC) between January 2015 and March 2024. Patient without complete stone removal during initial ERCP were included. Clinical success, adverse events, recurrent biliary obstruction (RBO), and time to RBO (TRBO) were compared in 21 patients treated with straight plastic stents (STs) under similar conditions.

resultsClinical success was achieved in 99% of patients in the DHP group and 95% of the ST group (p=0.13). Adverse event rates were comparable between groups. During follow-up, the DHP group had significantly lower stent occlusion (2% vs. 20%, p<0.01) and migration rates (4% vs. 15%, p=0.02), leading to a lower RBO rate (5% vs. 35%, p<0.01). The median TRBO was significantly longer in the DHP group (585 vs. 247 days, p<0.01).

conclusionsDHPs had comparable efficacy to STs, with significantly fewer stent-related adverse events. This may be a potential option for biliary drainage in ACC.
