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
introductionIpsilateral proximal and shaft femoral fractures are rare, high-energy injuries associated with substantial morbidity. Evidence on predictors of adverse outcomes after surgical treatment remains limited.
methodsWe conducted a retrospective cohort study at a tertiary trauma center including all skeletally mature patients who underwent surgical treatment for ipsilateral proximal femoral fractures (femoral neck or trochanteric region) associated with femoral shaft fractures between January 2019 and December 2024. The primary outcome was a composite of major complications, including deep surgical site infection, delayed union, nonunion, symptomatic pulmonary embolism, or all-cause mortality. Bivariable analyses were performed to compare patients with and without major complications, followed by multivariable logistic regression to identify independent predictors.
resultsFifty-two patients were included, with a mean age of 41.8 years and a mean Injury Severity Score (ISS) of 23.1. Major complications occurred in 17 patients (32.7%). The most frequent major complications were all-cause mortality (13.5%) and deep surgical site infection (11.5%). In bivariable analysis, smoking, longer time to definitive treatment, and higher ISS were associated with major complications. In the multivariable model, smoking (adjusted odds ratio [OR] 19.24, 95% confidence interval [CI] 2.78-133.04; p = 0.003) and higher ISS (adjusted OR per point 1.10, 95% CI 1.01-1.19; p = 0.027) remained independently associated with the primary outcome, whereas time to definitive treatment and age did not.
conclusionMajor complications were frequent after surgical treatment of ipsilateral proximal and shaft femoral fractures, affecting nearly one-third of patients. Smoking and greater trauma severity, as measured by ISS, were the main independent predictors of adverse outcomes. These findings highlight the importance of perioperative risk stratification and support smoking as a relevant modifiable risk factor in this setting.
