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: Femoral neck fractures (FNF) in older adults are frequently managed with either total hip arthroplasty (THA) or hemiarthroplasty (HA). Despite improvements in surgical techniques, mortality rates after hip fracture surgery remain high. Identifying predictors of early mortality may enhance surgical decision-making, optimize perioperative management, and improve patient outcomes. Purpose: The purpose of this study was to determine the short- and mid-term mortality rates after THA and HA for FNF, to identify clinical, demographic, and laboratory factors associated with 30-, 90-, and 180-day mortality, and to establish clinically relevant cutoff thresholds for significant continuous variables to stratify risk. Patients and methods: We retrospectively reviewed 2379 consecutive patients treated for sub-capital FNF at a tertiary trauma center between [insert study years]. Of these, 831 underwent THA and 1548 underwent HA. Mortality was assessed at 30, 90, and 180 days postoperatively. Demographic, clinical, and laboratory parameters were analyzed using univariate and multivariate logistic regression models. Receiver operating characteristic (ROC) curve analysis was performed to identify optimal cutoff thresholds for significant continuous predictors. Results: Among THA patients, mortality was 1.4 % at 30 days, 3.4 % at 90 days, and 5.1 % at 180 days. Postoperative albumin ≤2.85 g/dL predicted 30-day mortality, while C-reactive protein (CRP) > 19.15 mg/dL was independently associated with mortality at 90 and 180 days. Among HA patients, mortality was 6.6 % at 30 days, 12.9 % at 90 days, and 17.6 % at 180 days. Predictors of 30-day mortality included white blood cell count (WBC) > 14.48 × 10 Conclusions: This study identified several laboratory and clinical markers that predict short- and mid-term mortality following hip arthroplasty for FNF. Hypoalbuminemia, elevated inflammatory markers, renal dysfunction, and high comorbidity burden were consistent risk factors. Incorporating these parameters into preoperative assessment may improve patient selection, perioperative optimization, and shared decision-making. Level of Evidence: III.
