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

objectiveTo investigate the learning curve of transvaginal natural orifice transluminal endoscopic hysterectomy (tVNOTEH) when using a standard operating procedure (SOP).

methodsSeventy-nine patients were treated with tVNOTEH by a single surgeon. The SOP for tVNOTEH was created after the first eight cases. Patients' perioperative data were retrospectively reviewed. Operative time (OT) was regarded as a replaceable marker for surgical competency. The learning curve was drawn using the cumulative sum method.

resultsAll patients completed surgeries without switching to other surgical paths. The overall mean OT was 90.23 ± 29.85 min. Four unique phases of the learning curve were identified: phase I (the exploring stage over eight cases), phase II (after adopting the SOP, acquirement of competence over 20 cases), phase III (post-learning of 19 cases, in which more difficult cases were introduced), phase IV (more adept at tVNOTEH), with OT 113.75 ± 43.07 min, 82.50 ± 25.88 min, 101.05 ± 27.83 min, 82.75 ± 25.53 min, respectively. No significant differences were found apart from OT, uterine size, and disease types.

conclusionOur data demonstrated four distinct phases of the learning curve of tVNOTEH. For an experienced surgeon, surgical competence in tVNOTEH can be grasped after eight cases. With SOP, surgical competence could be rapidly acquired.
