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

backgroundRecent studies have reported conflicting data on the risk of postoperative complications in patients with Crohn's disease (CD) exposed to ustekinumab (UST) preoperatively. We performed a systematic review and meta-analysis to better assess and quantify the risk of postoperative complications in this population undergoing major abdomino-pelvic surgery.

methodsWe conducted a comprehensive search of multiple electronic databases and conference proceedings (earliest inception through October 2020) to identify studies that reported the postoperative outcomes in CD patients with preoperative UST exposure. We estimated and compared the pooled rates of postoperative complications, including intra-abdominal sepsis, surgical site infection, any infection, any adverse event, readmission, and reoperation.

resultsA total of 5 studies were included in the analysis. The last dose of the drug was at most 16 weeks prior to abdomino-pelvic surgery. A total of 172 CD patients (61% female; median age 35 years) were included. The pooled rate of any complication and any infectious complications was 23.5% (95% confidence interval [CI] 16-33.1) and 20.2% (95%CI 10.3-35), respectively. There was no difference in rates of intra-abdominal sepsis between the UST group (7.2%, 95%CI 3-16.4) and the anti-tumor necrosis factor (TNF) group (11.9%, 95%CI 5.9-22.5;

conclusionsThe postoperative complication rate in patients with preoperative UST exposure may be similar to that for anti-TNF medication. Preoperative exposure to UST does influence postoperative complication risk. Future prospective studies are needed to validate these findings.
