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

backgroundThe incidence and prevalence of Crohn's disease (CD) are increasing in China, but there are few reports on the characteristics of patients requiring abdominal surgery. This study aimed to evaluate the clinical characteristics of these patients and the potential risk factors for postoperative complications and surgical recurrence.

methodsIn this observational, retrospective single-center cohort analysis, patients with CD who had undergone at least one abdominal surgery at our center from 2007 to 2020 were included. Data were collected from a prospectively maintained database. Clinical factors were assessed by logistic regression models, Kaplan-Meier methods, and Cox proportional hazards regression models. The predictive accuracy of the nomogram was determined by a concordance index (C-index) and calibration curve and was validated using bootstrap resampling.

resultsIn the 1639 patients, clinical characteristics were evaluated. In a multivariable logistic regression model, penetrating behavior (P = 0.002), emergency surgery (P = 0.010), and smoking status (P = 0.015) were significantly associated with an increased risk of postoperative septic complications. In contrast, staged surgery (P = 0.009) was inversely associated with postoperative complications. Upper gastrointestinal disease (P = 0.042), penetrating behavior (P = 0.027), emergency at initial surgery (P < 0.001) were significantly associated with an increased risk of surgical recurrence after the index surgery in our Cox regression model, whereas staged surgery (P = 0.036) was significantly associated with a decreased risk. The C-index of the nomogram for predicting recurrence was 0.744 (P = 0.015), and calibration curves showed good agreement between predictions of 3, 5, and 10 years of recurrence and actual observations.

conclusionsThere are several disease- and surgery-associated risk factors of postoperative adverse outcomes in patients with CD undergoing abdominal surgery. This is important in optimizing the management of CD which has evolved into a global disease with rising prevalence in newly industrialized countries including China.
