Complicated appendicitis and surgical site infection associated with prolonged hospital stay after appendectomy in a Peruvian hospital.

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
Objective: To identify factors associated with prolonged hospital stay after appendectomy for acute appendicitis in a Peruvian public hospital. Methods: We conducted a retrospective case-control study of adults who underwent appendectomy for acute appendicitis at Hospital Jesús Nazareno, Ayacucho, Peru, between January 2021 and December 2024. Cases had a hospital stay of ≥5 days, corresponding to the 75th percentile of the institutional distribution, and controls had a stay of <5 days. From 96 eligible cases and 288 eligible controls, 73 patients from each group were selected by simple random sampling. Crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using logistic regression. Results: Median hospital stay was 6.0 days (IQR, 5.0-9.0) among cases and 2.0 days (IQR, 2.0-3.0) among controls. Complicated appendicitis was more frequent among cases than controls (97.3% vs. 27.4%), as was surgical site infection (38.4% vs. 1.4%). After multivariable adjustment, complicated appendicitis (adjusted OR, 38.62; 95% CI, 7.78-191.82) and surgical site infection (adjusted OR, 9.58; 95% CI, 1.14-80.55) remained associated with prolonged hospital stay. Conclusion: Complicated appendicitis and surgical site infection were associated with prolonged hospital stay after appendectomy. Because the timing of surgical site infection onset was not captured, its temporal relationship with prolonged stay cannot be established. Timely management of complicated appendicitis and adherence to perioperative infection-prevention practices may help reduce prolonged hospitalization.
