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

backgroundTo assess and compare the efficiency and outcomes between prone split-leg position and lithotomy position in posterior uterine myomectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES).

methods33 patients with posterior uterine myomectomy by vNOTES in the prone split-leg position and 15 patients in the lithotomy position were retrospectively recruited. Important baseline characteristics and outcome parameters such as age, body mass index, volume of myoma, delivery mode, hospital length, intraoperative blood loss, hemoglobin values before and 72 h after operation, VAS score, operation time and operation preparation time were compared between two patient groups.

resultsThe operation time of the prone split-leg position group was significantly shorter than that of the lithotomy position group (P < 0.05), but the operation preparation time of the prone split-leg position group was longer than that of the lithotomy position group (P < 0.05). No significant difference was found in other indicators between the two patient groups.

conclusionsOur study suggests the potential application of the prone split-leg position in posterior uterine myomectomy by vNOTES.
