Postbiliary drainage rates of cholangitis are impacted by procedural technique for patients with supra-ampullary cholangiocarcinoma: A SEER-Medicare analysis.

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.
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
backgroundThe optimal approach to biliary drainage for patients with supra-ampullary cholangiocarcinoma remains undetermined. Violation of sphincter of Oddi results in bacterial colonization of bile ducts and may increase postdrainage infectious complications. We sought to determine if rates of cholangitis are affected by the type of drainage procedure.
methodsWe examined the Surveillance, Epidemiology, and End Results-Medicare linked database from 1991 to 2013 for cholangiocarcinoma. Biliary drainage procedures were categorized as sphincter of Oddi violating (SOV) or sphincter of Oddi preserving (SOP). Patients were stratified by resection.
resultsA total of 1914 patients were included in the final analysis. A total of 1264 patients did not undergo a postdrainage resection (SOP 83, SOV 1181) while 650 did undergo a postdrainage resection (SOP 26, SOV 624). For those patients not undergoing a postdrainage resection, the rate of cholangitis 90 days after an SOP procedure was 19% compared with 34% in the SOV cohort (P = 0.007). For those patients undergoing a postdrainage resection, the rate of cholangitis 90 days after an SOP procedure was less than 42.3% compared with 30% in the SOV cohort (P = 0.66).
conclusionFor patients with supra-ampullary cholangiocarcinoma that did not undergo resection, biliary drainage procedures that violated the sphincter of Oddi were associated with increased rates of cholangitis.
