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

Background: We evaluated the association between rectus femoris muscle thickness adjusted by body mass index (RFT/BMI) and oxygen uptake at anaerobic threshold (AT-V̇O Methods and Results: In this retrospective cross-sectional study, 103 patients with HF who underwent ultrasound-derived RFT measurement and cardiopulmonary exercise testing (CPX) were included. RFT/BMI was examined using multivariable linear regression and restricted cubic spline analysis. Receiver operating characteristic curve analysis identified optimal RFT/BMI cutoffs, and propensity score-adjusted modified Poisson regression assessed associations with subthreshold AT-V̇O Conclusions: Ultrasound-derived RFT/BMI was associated with AT-V̇O
