Daytime versus nighttime appendectomy in term of complications and clinical outcomes: a meta-analysis.
Synthesis in International journal of colorectal disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 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
backgroundAppendicitis is one of the most common acute surgical conditions globally. However, the association between nighttime appendectomy and patients' morbidity and mortality is unclear. This study aims to compare outcomes following nighttime versus daytime appendectomy.
methodsThe PubMed, Embase, Cochrane Library, and Web of Science databases up to March 26, 2024 (updated on July 1, 2024) were searched. The primary outcomes were postoperative complications and mortality. Secondary outcomes included intraoperative complications, reoperation, readmission, conversion to laparotomy, hospital stay and operation time. Mean difference (MD) or odds ratios (OR) and 95% confidence intervals were calculated.
resultsFifteen studies totaling 33,596 patients were included. There were no differences between nighttime and daytime appendectomy for rates of overall postoperative complications (OR 0.93, 95% CI 0.87, 1.00, 14 studies), mortality (OR 1.70, 95% CI 0.37, 7.88, 7 studies), intraoperative complications (OR 0.88, 95% CI 0.08, 9.86; 2 studies), reoperation (OR 0.39, 95% CI 0.06, 2.55; 3 studies) and readmission (OR 0.86, 95% CI 0.65, 1.13; I
conclusionsThere was no increased risk or difference in postoperative mortality and complication rates associated with nighttime compared with daytime appendectomy. However, future studies should assess the reasons for higher conversion rates during the night.
