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

purposeThe aim of this study was to estimate efficacy of mechanical bowel preparation with polyethylene glycol (PEG) in prevention of postoperative complications in elective colorectal surgery.

methodA literature search of MEDLINE (PubMed), EMBASE, and the Cochrane Library was done to identify randomized controlled trials involving comparison of postoperative complications after mechanical bowel preparation with PEG (PEG group) and no preparation (control group). A meta-analysis was set up to distinguish overall difference between the two groups.

resultsA total of five randomized controlled trials was identified according to our inclusion criteria. The use of PEG for mechanical bowel preparation did not significantly reduce the rate of surgical site infection (SSI; odds ratio (OR) 95% confidence interval (CI), 1.39 (0.85-2.25); P = 0.19) including incisional SSI (OR 95% CI, 1.44 (0.88-2.33); P = 0.15), organ/space SSI (OR 95% CI, 1.10 (0.43-2.78); P = 0.49), anastomotic leak (OR 95% CI,1.78 (0.95-3.33; P = 0.07), mortality (OR 95% CI, 1.24 (0.37-4.14; P = 0.73), infectious complications (OR 95% CI, 1.14 (0.62-2.08); P = 0.67), and hospital stay (weighted mean difference 95% CI, 2.17 (-2.90-7.25); P = 0.40) except main complications (OR 95% CI, 1.76 (1.09-2.85); P = 0.02), of which the rate increased significantly in the PEG group.

conclusionThe use of mechanical bowel preparation with PEG does not significantly lower postoperative complications in elective colorectal surgery.
