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
introductionPeriprosthetic femoral fractures (PPFs) are an increasing cause of revision total hip arthroplasty (THA) and mainly affect an elderly and frail population. When femoral stem revision is required, surgical management remains associated with substantial morbidity and mortality. However, it remains unclear whether postoperative mortality is primarily driven by patient-related characteristics or by surgery-related factors. PURPOSE: To identify time-dependent prognostic factors for mortality during the first postoperative year following femoral stem revision for PPF. MATERIAL AND
methodsA retrospective single-centre consecutive series of 398 PPFs treated with femoral stem revision between January 2011 and August 2023 was analysed. Mean age was 81 years (± 11), and 59% of patients had an ASA score ≥ 3. Mortality risk factors were evaluated at 30 days, three months, six months, and one year using multivariate analysis.
resultsOne-year mortality was 20.4%. Male sex, older age, and a higher ASA class were independent predictors of mortality at all evaluated postoperative time points. Low BMI emerged as an additional independent predictor of year mortality. Although several clinical and surgical variables were associated with mortality in univariate analyses, only patient-related factors remained independently associated with mortality after multivariable adjustment.
conclusionMortality following femoral stem revision for PPF remains high in this elderly and vulnerable population. Patient-related factors, particularly older age, higher ASA class, male sex, and low BMI, were the main independent predictors of postoperative mortality, whereas surgical variables were not independently associated with survival after adjustment. These findings highlight the predominant role of baseline patient frailty and may help improve perioperative risk stratification and multidisciplinary management.
