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 study examined whether urgency of surgical intervention affects postoperative outcomes in patients with Crohn's disease (CD) undergoing bowel resection.

methodThe review was conducted according to a predefined, published study protocol in Prospero which is an international database of prospectively registered systematic reviews in health. The study reported according to PRIMSMA guidelines. We searched Embase and Pubmed for articles reporting postoperative outcome after urgent and elective surgery in patients with CD undergoing bowel resection. Primary outcome variable was 30-day overall postoperative complications while secondary outcome variables were intraabdominal septic complications (IASCs), mortality, reoperation, and readmission. Assessment of bias was performed using Newcastle-Ottawa score. Two authors independently extracted data on each study, patients, and outcome measures.

resultsThe search identified 22 studies in which 955 patients underwent urgent surgeries while 6518 patients underwent elective surgeries. Based on the quality assessment, 19 studies were classified as having high risk of bias, one study as having a medium risk of bias and 2 studies as having low risk of bias (≥ 8 stars). Random-effect metaanalysis showed urgent surgery was associated with ~ 40% increase in overall complications compared to elective surgery (RR = 1.43, 95% CI [1.09; 1.87], p = 0.010). IASCs also increased in patients who had urgent surgery (RR = 1.44, 95% CI [1.08; 1.92], p = 0.013). No significant difference was shown in mortality and readmission rates.

conclusionUrgent bowel resection in patients with CD is associated with higher risk of overall postoperative complications and IASCs.
