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

backgroundPrimary closure after laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) is a safe and effective approach for treating cholecystolithiasis with choledocholithiasis. The aim of this study was to evaluate the learning curve of performing primary closure after LC+LCBDE.

methodsWe retrospectively identified all patients who underwent primary closure after LC+LCBDE performed by a single surgeon from January 2009 to April 2015 in our institution, and analyzed preoperative, intraoperative, and postoperative data using the cumulative sum (CUSUM) analysis to evaluate the learning curve for this procedure.

resultsOverall, there were 390 patients. The total postoperative complications rate was 7.2%, including bile leakage in 9 (2.3%) patients and retained common bile duct stone in 3 (0.8%) patients. The CUSUM operating time (OT) learning curve was best modeled by the equation: CUSUM

conclusionThe data suggest that the learning curve of this procedure was achieved in approximately 54 cases. An impacted stone was the only risk factor that affected the conversion rate.
