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.

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.

Abstract

backgroundTraditional teaching has been to place patients in the left lateral decubitus starting position for colonoscopies. Recent randomized controlled trials (RCTs) have compared left lateral decubitus starting position to other approaches. The aim of this systematic review and meta-analysis was to compare different starting positions for colonoscopies and their effect on cecal intubation.

methodsMEDLINE, Embase, and CENTRAL were searched from inception to July 2023. Articles were eligible for inclusion if they were RCTs comparing at least two different starting positions for adults undergoing colonoscopy. The main outcome was cecal intubation time. Meta-analysis used an inverse variance random effects model. Risk of bias was assessed with the Cochrane Tool for RCTs 2.0.

resultsAfter screening 1523 citations, 14 RCTs were included. Four studies compared left lateral decubitus to right lateral decubitus, four studies compared left lateral decubitus to left lateral tilt-down, three studies compared left lateral decubitus to prone, and three studies compared left lateral decubitus to supine. There were no statistically significant differences in cecal intubation time in seconds across all comparisons: left lateral decubitus vs. right lateral decubitus (MD 14.9, 95% CI - 111.8 to 141.6, p = 0.82, I

conclusionThe starting position for colonoscopies likely does not influence cecal intubation time. This study was limited by heterogeneity.
