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 debate whether laparoscopic pyloromyotomy (LP) is superior to open pyloromyotomy (OP) remains actual. A recent review showed no benefit between the LP or OP, but in the studied randomized, controlled trials the learning curve was not addressed. Comparing LP including the learning curve with OP after the learning curve is questionable. In previous research, the learning curve of LP was analyzed. It was concluded that the plateau was reached after 35 procedures with a steep decrease in complications when comparing before and after 35 procedures. This study was designed to retrospectively analyze the results obtained in HPS patients after the learning curve in LP has been reached. The results will be compared with results of OP in HPS patients in the same period.

methodsA retrospective analysis in 106 OP and 57 LP was performed from September 2008 to June 2012.

resultsThe overall complication rate in the OP group was significantly higher than in the LP group (18% vs. 3.5%, p = 0.012). Also there was a higher major complication rate in the OP group (10.4% vs. 1.7%, p = 0.045). The median time to operate was with 28.5 min in OP and 30.0 min in LP (not significant), whereas the LOS was 2 days in both groups (not significant).

conclusionIn this study, a further decline in overall and major complications after the learning curve is seen in the LP group, the tail of the learning curve. The debate whether LP is superior to OP is not finished as long as it is not clear whether the minimally invasive operation is beyond the initial or tail of the learning curve.
