Prevalence of osteosarcopenia in patients with end-stage knee OA who underwent total knee arthroplasty.

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
This study investigated the prevalence of osteoporosis and sarcopenia in patients with end-stage knee osteoarthritis (OA) undergoing total knee arthroplasty (TKA).
methodsIn this retrospective cohort study, all patients with end-stage knee OA who underwent TKA between April 2022 and May 2023 were included. Preoperative appendicular lean mass index and bone mineral density were measured using dual-energy X-ray absorptiometry.
resultsA total of 1755 patients (mean age, 73.5 ± 6.8 years) underwent TKA, with women comprising the majority (1554 patients, 88.5%). The prevalence of osteoporosis and sarcopenia was significantly higher in women than in men. Osteoporosis affected 51.9% of women versus 21.4% of men, and sarcopenia affected 42.2% of women versus 36.3% of men. The prevalence of osteosarcopenia was more than twice as high in women (25.9%) as in men (11.4%).
conclusionOsteosarcopenia was present in 24.1% of patients with end-stage knee OA undergoing TKA, exceeding rates in the general population. The condition was particularly prevalent among elderly female patients.
