Beyond BMI: A Cross-Sectional Analytical Study of the Association Between Body Composition Parameters and Functional Disability in Overweight and Obese Adults With Chronic Low Back Pain.

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
Background Low back pain (LBP) is a significant cause of global disability and is closely associated with overweight and obesity due to increased mechanical load, chronic inflammation, and altered muscle function. The body mass index (BMI) fails to differentiate between fat and lean compartments, thereby limiting its clinical utility. Evidence on the association between specific body composition parameters, such as body fat mass index (BFMI), fat-free mass index (FFMI), and lean body mass (LBM), and functional disability in the Indian population remains scarce. Materials and methods This cross-sectional study included 99 overweight and obese adults with chronic LBP attending a tertiary care teaching hospital in South India, recruited through convenience sampling. Body composition was assessed using bioelectrical impedance analysis, and functional disability was evaluated with the Oswestry Disability Index (ODI). Pearson correlation and linear regression analyses were performed to assess associations between body composition parameters and disability. Results The mean age of participants was 47.6 ± 9.5 years, with females comprising 94.9% of the sample. Obesity was prevalent in 70.7% of participants, and most reported severe pain with long symptom duration. Severe functional disability was observed in 68.7% of cases. ODI showed strong negative correlations with LBM (r = -0.67
