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 learning curve of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery has been well investigated. The learning curve is defined by complications and/or by duration of surgery (DOS). Previous studies report an inverse relationship between patient outcome and patient volume. In this study, we investigate whether the learning curve of preceding bariatric surgeons is of additional influence for surgeons who start to perform LRYGB in the same centre. MATERIALS AND

methodsWe retrospectively analysed the records of all 713 consecutive primary LRYGB patients operated in our centre from December 2007 until July 2012. Surgeon 1 and 3 had previous laparoscopic bariatric experience whilst Surgeon 2 and 4 had not. We stratified the data between the four surgeons with different levels of experience and in a chronology of 50 cases.

resultsSixty-seven (9.4 %) complications occurred in the study period. Surgeon 1 had more complications occurring within the first 50 cases than Surgeon 4 (10 versus 1, p < 0.05). There was no difference in complication rate between groups of 50 consecutive cases. None of the patients died. DOS decreased for every consecutive surgeon, irrespective of their experience. The learning curve defined by DOS was steepest for Surgeon 1, followed by Surgeon 2, 3 and 4.

conclusionIn this study, we show that the learning curve of the preceding surgeon positively influences the learning curve of latter surgeons, irrespective of their experience. Therefore, the 'preceding surgeon factor' should be taken in account in addition to volume requirements when starting new bariatric facilities.
