1 · What the graph read from it

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.

2 · The registry

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

Sarcopenia diagnosed via opportunistic computed tomography (CT) is linked to poor postoperative outcomes. This study aimed to investigate the association between chest CT-diagnosed sarcopenia and post-total knee arthroplasty (TKA) functional outcomes. This single-center retrospective cohort study included 158 knee osteoarthritis (KOA) patients who underwent primary TKA between January 2021 and June 2022. Sarcopenia was defined using skeletal muscle index values derived from chest CT images at the T12 vertebral level. Sociodemographic, clinical, and perioperative data were collected, and functional outcomes were assessed via the Hospital for Special Surgery (HSS) score at 6 months postoperatively. Univariate and multivariate analyses identified independent risk factors for poorer postoperative functional outcomes in KOA patients undergoing TKA. The prevalence of sarcopenia in the cohort was 48.7%. At 6 months after TKA, sarcopenic patients had significantly lower HSS scores (P < 0.05). Advanced age (P = 0.025), higher body mass index (P = 0.027), sarcopenia (P = 0.020), and higher postoperative pain scores (P < 0.001) were independently associated with poorer functional outcomes. The results indicate that chest CT-determined sarcopenia is prevalent among KOA patients undergoing TKA and is significantly associated with poorer functional outcomes.
