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

backgroundRoux-en-Y gastric bypass (RYGB) is well-established for its effectiveness in promoting weight loss and improving metabolic health, but its effects on muscle mass, strength, physical function, and quality of life (QoL) remain unclear. This study aimed to compare and explore the associations between muscle mass, muscle strength, physical function, and QoL indicators in patients who underwent RYGB and in matched non-surgical controls.

methodsThis cross-sectional study included 39 patients post-RYGB (92.3% females, aged 39 ± 5 years, and BMI of 42.2 ± 3.8 kg/m

resultsCompared to controls, patients who underwent RYGB showed similar ASM index (7.13 [6.65-7.85] vs. 7.41 [6.84-8.18] kg/m

conclusionsMuscle health appears to be preserved following RYGB. However, the observed impairments in QoL indicators highlight the need for post-surgical care to extend beyond weight loss and metabolic improvements, addressing both physical and psychological well-being.
