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
backgroundFemoral fractures are high-impact injuries commonly arising from traffic collisions, falls, and other trauma mechanisms. Surgical site infection (SSI) following fixation remains a major postoperative complication, amplified by soft-tissue disruption, environmental contamination, and prolonged hospitalization. Evidence on how mechanism of injury (MOI) moderates SSI risk, pathogen distribution, and antimicrobial resistance (AMR) patterns in trauma populations remains limited.
methodsWe conducted a 5-year retrospective cohort study (2020-2024) at a tertiary trauma centre including all operatively managed femoral fractures. MOI categories comprised traffic accidents, falls, sports injuries, violence, work-related trauma, and firearm injuries. Demographic, clinical, surgical, and microbiological data were obtained from a prospectively maintained registry. SSI was defined according to the 2018 AO/EBJIS Fracture-Related Infection (FRI) consensus criteria. Group comparisons used χ
findingsOf 2891 patients, 249 developed SSI (8.6%). Gram-negative organisms predominated, with A. baumannii accounting for most isolates across MOI groups, while S. aureus was more common in younger and sports-related injuries. Resistance testing showed persistently high multidrug resistance (MDR, 66.2%), with declining trends in extensively drug-resistant (XDR) phenotypes and carbapenem resistance over time. Independent predictors of SSI included ASA ≥ 3, diabetes mellitus, preoperative anaemia, and operative duration > 90 min. SSI markedly increased reoperation rates and more than doubled 1-year mortality.
conclusionMOI shapes both SSI risk and microbiological profiles following femoral fracture surgery. The dominance of Gram-negative organisms and high MDR burden highlight the need for MOI-specific prevention strategies and trauma-adapted antimicrobial stewardship.
