Hamstring strength and hip mobility associated with pain and disability in lumbar instability.

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.
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
Chronic low back pain (LBP) has been hypothesized to involve lumbar instability, yet the roles of hamstring strength and hip mobility remain underexplored. While earlier studies focused on hamstring tightness, this study examined how these factors are strongly associated with pain and disability in young adults with lumbar instability. A case-control study was conducted on 129 participants (67 symptomatic, 62 asymptomatic) aged 18-35 years. Hamstring strength was assessed using the NordBord dynamometer, while hip mobility was measured using a goniometer. Pain intensity and disability were evaluated using the Numeric Pain Rating Scale and Oswestry Disability Index. Hamstring strength showed a strong negative correlation with pain (r = -0.71, p < 0.001) and disability (r = -0.72, p < 0.001). Regression analysis confirmed hamstring strength and hip mobility as key correlates of LBP severity. Cutoff values were determined for hamstring strength (Female: 178.0 N; Male: 197.5 N), hip internal rotation (Female: 23°; Male: 18°), and hip extension (Female: 21°; Male: 19°). Hamstring strength and hip mobility are key correlates of pain and disability in young adults with clinically defined lumbar instability. Candidate thresholds showed apparent in-sample discrimination and should be interpreted as hypothesis-generating rather than diagnostic.
