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

purposeSingle-incision laparoscopic surgery (SILS) for colon cancer is technically challenging for novice surgeons. Although it has been shown to be safe and feasible, the learning curve (LC) among novices has not been characterized. The present study investigated the LC for SILS based on data from several novice surgeons.

methodsWe retrospectively reviewed consecutive cases of SILS-ileocecal resection (SILS-ICR) performed by two experienced and three novice surgeons from May 2009 to March 2020. A cumulative sum (CUSUM) analysis was used to analyze the learning curve and evaluate SILS completion. In addition, a statistical model was created to clarify the difference between the operation times of novices (Surgeons C, D, and E) and experienced surgeons (Surgeons A and B), estimating the operative time and risk estimation model.

resultsTwo experienced surgeons and three novice surgeons performed 187 and 103 SILS-ICRs, respectively. A CUSUM analysis showed LCs of 20, 18, and 20 cases for Surgeons C, D, and E, respectively, suggesting that novice surgeons would achieve results comparable to those of experienced surgeons in 39, 47, and 36 cases, respectively.

conclusionsIn SILS-ICR, novice surgeons reached the nadir in 18-20 cases and reached the level of experienced surgeons in 36-47 cases.
