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

backgroundSelf-expandable metallic stents (SEMSs) are recommended for preoperative biliary drainage in patients with pancreatic cancer. However, they are associated with a relatively high incidence of non-recurrent biliary obstruction (RBO) adverse events (AEs), such as pancreatitis and cholecystitis. The 11.5-Fr large-bore plastic stent (LBPS) is a newly developed stent with a larger diameter than conventional plastic stents. The aim of the present study was to compare the clinical outcomes of LBPS and SEMS in preoperative biliary drainage for pancreatic cancer.

methodsWe retrospectively evaluated 80 patients who underwent preoperative biliary drainage for pancreatic cancer between January 2011 and December 2025. Patients were divided into the LBPS and SEMS groups according to the stent placed.

resultsRBO occurred in 20.0% and 25.0% of patients in the LBPS and SEMS groups, respectively, with no significant difference in the time to RBO between the groups. Pancreatitis and cholecystitis were observed in 0% versus 18.3%, and 0% versus 8.3% of patients in the LBPS and SEMS groups, respectively.

conclusionThe 11.5-Fr LBPS demonstrated patency comparable to that of SEMS and was associated with a low incidence of non-RBO AEs. These findings should be interpreted cautiously and require confirmation in larger prospective studies.
