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
introductionDespite extensive evidence demonstrating lower complications with cemented hip hemiarthroplasty (HHA), many orthopaedic surgeons continue to use noncemented HHA implants for the management of femoral neck fractures in elderly populations. In this study, we aimed to validate these findings within our cohort and to examine whether this evidence is reflected in current surgical practice.
methodsWe conducted a retrospective cohort study of patients aged older than 50 years who underwent HHA for intracapsular femoral neck fractures between 2009 and 2018 across a multicenter hospital system. Intraoperative and postoperative surgical complications were compared between cemented and noncemented implants. Surgeon data, including fellowship training and case volume, were collected to assess associations with implant selection.
resultsA total of 4407 patients (mean age 81 years, mean follow-up 4106 days) were included, with 496 (11%) receiving cemented and 3911 (89%) noncemented HHA. Intraoperative and postoperative periprosthetic fractures were significantly lower in the cemented group (HR = 0.57, 95% CI, 0.32-0.82, P = 0.047; and HR = 0.39, 95% CI, 0.17-0.77, P = 0.021, respectively). Use of cemented over noncemented HHA was significantly higher among trauma surgeons (36.4%) compared with arthroplasty surgeons (4.3%, P = 0.012), and general orthopaedic surgeons or surgeons with nonrelated fellowship training (7.1%, P = 0.029).
conclusionConsistent with previous studies, our findings reaffirm the superior clinical outcomes of cemented HHA. Nevertheless, noncemented implants remained the predominant choice within our hospital system-even among fellowship-trained surgeons. This highlights a persistent gap between evidence and practice, emphasizing the need for stronger integration of evidence-based guidelines into surgical decision making. LEVEL OF EVIDENCE: Level III.
