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

Muscle ageing involves structural and functional changes of muscles, mainly their replacement by fatty and fibrous tissue accompanied by the loss of muscle function. Quantitative magnetic resonance imaging (qMRI) methods have potential to provide biomarkers of degenerative changes in muscles with ageing. To assess the relationship between qMRI parameters of lumbar paraspinal muscles (LPMs) and their function and evolution with ageing in healthy subjects, 90 volunteers underwent MRI of lumbar spine and LPM utilising a 6-point Dixon gradient echo sequence. Using manual muscle segmentation, fat fraction (FF) and functional muscle volume (FMV) were calculated for LPM, with the psoas muscle (PS) as a control muscle. Functional parameters of LPM (strength and endurance) were assessed. Based on our data analysis, both FF and FMV of LPM correlate significantly with maximal isometric lumbar extensor muscle strength, but not with endurance. With ageing, FF of LPM increases by 34% per decade, while FF of PS increases by 17% per decade. This difference between LPM and the PS in the rate of FF increase is significant. FMV evinces a decreasing trend in both LPM and PS. However, only FMV of PS decreases significantly by 7% per decade. Our cross-sectional study shows a significant correlation between qMRI parameters of LPM and their strength. FF appears to be a biomarker of muscle ageing with different ageing patterns of distinct muscle groups: LPM and PS.
