Interrelationships among handgrip strength, body composition, physical activity, and quality of life in adults with cystic fibrosis: A cross-sectional study.

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
backgroundIn individuals with cystic fibrosis (CF), lean mass and muscle strength are important predictors of clinical outcomes. This study evaluated associations among body composition, handgrip strength, muscle quality, physical activity, and health-related quality of life in CF.
methodsThis observational, cross-sectional study included 27 adults with CF and 24 age-matched healthy controls. Body composition was assessed using dual-energy x-ray absorptiometry, physical activity by self-reported questionnaire, strength by handgrip dynamometry, and quality of life by the CF Quality of Life-Revised (CFQ-R) questionnaire. Muscle quality was defined as handgrip strength divided by appendicular lean mass. Analyses included t- tests and Pearson or Spearman correlations.
resultsDemographics, body composition, handgrip strength, and muscle quality were similar between those with CF and controls. Among those with CF, muscle quality was positively associated with total physical activity score (r = 0.49, P = 0.009). Handgrip strength was positively associated with lean mass (r = 0.86, P < 0.001) and bone mineral density (r = 0.64, P < 0.001). Regarding CFQ-R, lean mass was positively associated with body image and emotion (r = 0.41, P = 0.03), and body fat was associated with lower physical functioning (r = -0.63, P = 0.004), greater treatment burdens (r = -0.49, P = 0.01), and worse digestive health (r = -0.45, P = 0.02).
conclusionAs the CF population ages, these data support continued efforts to promote physical activity and improve body composition for enhanced quality of life while also highlighting the value of integrating accessible measures of muscle function and quality into routine clinical care.
