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

objectivesChronic low back pain (cLBP) is a major contributor to global disability. This study examined the association between paraspinal muscle morphology and spinal mobility and alignment in individuals with and without cLBP. MATERIALS AND

methodsIn this cross-sectional study, participants were prospectively recruited from the general population. Magnetic resonance imaging (MRI) was used to assess morphological characteristics, namely fatty infiltration (FI) and functional cross-sectional area (fCSA) of the multifidus (MF), erector spinae (ES), and psoas muscles at all lumbar levels individually and averaged. Lumbar mobility (flexion, extension, side-bending) was assessed with a skin surface measurement device. Associations between both parameters were evaluated using multivariable regression models adjusted for demographic, structural, and clinical confounders.

results721 participants (56.9% females, 226 without cLBP, 495 with cLBP) with a mean age of 41.8 (SD 12.1) were included. Average MF FI showed the strongest association with flexion in the cLBP group (ß: -0.50, 95% CI-0.66 - -0.34, p < 0.001, η²=0.071), exceeding the influence of age, disc degeneration, and pain intensity. This association was also significant in asymptomatic participants, though weaker (ß: -0.40, 95% CI -0.66 - -0.14, p = 0.003, η²=0.041). Level-specific differences were observed, with MF fCSA at L4/5-L5/S1 and ES fCSA at upper levels showing the strongest association with lumbar mobility.

conclusionMRI-based morphology of paraspinal muscles is associated with spinal mobility in both cLBP and asymptomatic individuals, independent of key confounders. Associations were level-, muscle-, and movement-specific, with the strongest effects observed for MF FI and lumbar flexion.
