Delayed return of bowel function after general surgery in South Australia.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Reference ranges for determining pathological versus normal postoperative return of bowel function are not well characterised for general surgery patients. This study aimed to characterise time to first postoperative passage of stool after general surgery; determine associations between clinical factors and delayed time to first postoperative stool; and evaluate the association between delay to first postoperative stool and prolonged length of hospital stay. Methods: This study included consecutive admissions at two tertiary hospitals across a two-year period whom underwent a range of general surgery operations. Multivariable logistic regression analyses were conducted to determine associations between the explanatory variables and delayed first postoperative stool, and between delayed first postoperative stool and length of hospital stay. The previously specified explanatory variables were used, with the addition of the dichotomised ≥4-day delay to first postoperative stool. Prolonged length of hospital stay was considered ≥7 days. Results: 2,212 general surgery patients were included. Median time to first postoperative stool was 2.28 (IQR 1.06-3.96). Median length of stay was 7.19 (IQR 4.50-12.01). Several operative characteristics and medication exposures were associated with delayed first postoperative stool. There was a statistically significant association between delayed first postoperative stool (≥4 days) and prolonged length of stay (≥7 days) (OR 4.34, 95 %CI 3.27 to 5.77, Conclusions: This study characterised expected reference ranges for time to return of bowel function across various general surgery operations and determined associations with clinical factors that may improve efficiency and identification of pathology within the postoperative course.
