Weekend Effect and Mortality After Emergency Laparotomy: A Retrospective Cohort Study With Complimentary Meta-Analysis.
Synthesis in ANZ journal of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
aimsTo evaluate the prognostic significance of the weekend effect in patients undergoing emergency laparotomy.
methodsA STROCSS-compliant retrospective cohort study (in three centres between January 2014 and January 2022) with complementary PRISMA-compliant meta-analysis (last search on 10 February 2025) was conducted. All adult patients undergoing non-traumatic emergency laparotomy were considered eligible. Emergency laparotomy during weekends (Saturday, Sunday and public holidays) was the prognostic factor of interest, and emergency laparotomy during weekdays (Monday, Tuesday, Wednesday, Thursday and Friday) was the comparison. Thirty-day mortality was the outcome.
resultsThe cohort study included 1952 patients and a search of electronic databases identified five retrospective cohort studies including 5374 patients. Consequently, 7326 patients (weekend group: 2035; weekdays group: 5291) were included for analyses. Both groups were comparable in terms of median age (67 years vs. 65, p = 0.194), being an octogenarian (17.9% vs. 17.9%, p = 0.970), male sex (41.9% vs. 45.7%, p = 0.153), ASA I status (4.5% vs. 6.7%, p = 0.080), ASA II (33.6% vs. 35.2%, p = 0.524), ASA III (46.6% vs. 41.6%, p = 0.060), ASA IV (14.7% vs. 15.2%, p = 0.764), ASA V (0.6% vs. 1.3%, p = 0.249), need for bowel resection (54.0% vs. 57.6%, p = 0.172) and peritoneal contamination (26.4% vs. 29.2%, p = 0.236). There was no difference in the risk of 30-day mortality between the two groups (OR: 1.04, 95% CI 0.87-1.25, p = 0.650; I
conclusionsRobust evidence with high certainty suggests that the weekend effect does not influence the risk of mortality after emergency laparotomy. This could be explained by the standardisation of perioperative care in patients undergoing emergency laparotomy.
