Direct medical costs and length of stay associated with postoperative systemic infectious complications after gynecologic surgery: a propensity score-matched case-control study.

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
Background and aim: To quantify the independent impact of postoperative systemic infectious complications (PSIC) on direct medical costs and length of stay (LOS) for patients undergoing gynecologic surgery. Methods: This was a retrospective case-control study conducted at a large tertiary healthcare facility in southwestern China. The participants included patients who underwent gynecologic surgery between January 2022 and December 2024. The study included 202 patients with PSIC (case group) and 600 matched patients without PSIC (control group) following 1:3 propensity score matching (PSM). The primary outcomes measured were direct medical costs and LOS, analyzed via a doubly robust estimation framework using Generalized Linear Models (GLMs) to calculate the Average Marginal Effect (AME). Results: After matching, baseline covariates were largely balanced, with any residual confounding addressed in downstream models. Total unadjusted direct medical costs were significantly higher in the PSIC group compared with the control group (median ¥31,124.06 vs. ¥20,726.43, Conclusion: PSIC following gynecologic surgery independently and substantially increases direct medical costs and prolongs hospitalization. These findings highlight the significant economic burden of these complications and underscore the value of investing in effective infection prevention strategies to optimize resource utilization.
