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

backgroundThe results in the literature regarding the learning curve (LC) of laparoscopic sleeve gastrectomy (LSG) are scarce and non-definitive. The purpose of the study was to evaluate the correlation between the LSG learning curve and intraoperative parameter variation, postoperative morbidity, weight loss results, and economic impact.

methodsThe first 99 obese patients undergoing LSG surgery by the same surgeon from March 2013 to April 2016 were included in the present study. Patients were equally distributed among three groups (A, B, C) based on case sequence.

resultsThe three study groups were homogeneous with respect to age, BMI, gender, and comorbidities. There was a significant reduction in operative time among the groups (p < 0.00001), with a difference of approximately 40 min between the first and third groups. The decrease in operative time was associated with a decrease in the number of stapler firings used per LSG. Conversely, there was no statistical correlation between intraoperative blood loss, intraoperative complications, or weight loss 1-year postsurgery and the LSG learning curve. In addition, the increase in experience with LSG was also associated with a significant reduction (p < 0.00001) in the length of hospital stay. With respect to postoperative complications, a statistically significant difference was recorded between groups B and C (p = 0.02). Finally, a patient undergoing surgery at the end of the LC had an estimated reduction in economic impact of approximately 2700 Euros compared with a patient undergoing surgery at the beginning of the LC.

conclusionApproximately 60 cases are required to reach proficiency in reducing postoperative complications and costs of LSG.
