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
introductionOptimal femoral stem fixation for hemiarthroplasty in older adults with displaced intracapsular fractures remains controversial. Cemented stems may reduce mechanical failure, but cementation carries risks. This study compared mortality and complications after cemented versus uncemented hemiarthroplasty in patients aged 75 years or older.
methodsWe performed a retrospective study of consecutive patients aged 75 years or older who underwent hemiarthroplasty for intracapsular fracture between January 2015 and April 2022. Patients were grouped by stem fixation and followed until death or censoring in December 2025, allowing at least three years of follow-up. Outcomes included periprosthetic femoral fracture, dislocation, periprosthetic joint infection, a composite of any complication, and all-cause mortality from the early postoperative period to 3 years. Multivariable Cox regression was used for 3-year mortality, and a Fine-Gray competing risk model, with death as the competing event, was used for 3-year complications.
resultsWe included 531 patients (266 cemented, 265 uncemented). Periprosthetic femoral fracture was more frequent with uncemented stems (4.5% vs. 1.5%, p = 0.042), whereas dislocation was more frequent with cemented stems (6.4% vs. 2.6%, p = 0.038). Periprosthetic joint infection and any complication did not differ significantly between groups at 1 or 3 years, and mortality did not differ at any assessed time point (all p > 0.05). Cemented fixation was not independently associated with 3-year mortality (HR 0.84, 95% CI 0.66-1.07; p = 0.166) or 3-year any complication (sHR 1.01, 95% CI 0.59-1.74; p = 0.977). Older age, male sex, and ASA class 3 to 4 independently predicted higher 3-year mortality. DISCUSSION: In patients aged 75 years or older, stem fixation was associated with different complication patterns, with more periprosthetic fractures after uncemented fixation and more dislocations after cemented fixation. Despite these differences in specific complications, cemented fixation was not independently associated with 3-year mortality.
