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

purposeTo investigate the relationship between skeletal muscle atrophy (SMA), assessed using chest CT-derived skeletal muscle index (SMI) at the T12 vertebra level, and 1-year mortality in geriatric patients following hip fracture surgery.

methodsAfter applying exclusion criteria, 1,243 patients (514 SMA) were analyzed. SMA was diagnosed by the skeletal muscle index at the T12 vertebral level (males: T12-SMI < 25.75 cm

resultsSMA was present in 41.4% of patients. The 1-year mortality rate was significantly higher in SMA patients compared to non-SMA patients (35.8% vs. 10.2%, p < 0.001). Lower T12-SMI levels were strongly associated with increased mortality, exhibiting a dose-response relationship. Multivariable-adjusted odds ratios for 1-year mortality decreased significantly across higher T12-SMI quartiles for both males and females.

conclusionsSMA, defined by low T12-SMI, is an independent predictor of 1-year mortality in geriatric hip fracture patients.
