Identifying sex-specific injury predictors as a key factor in maintaining optimal physical activity levels

Figure 1 Minimum sample size calculation. A: Formula; B: Calculation process for this study. p1, p2: Proportion (incidence) of groups #1 and #2; Δ = |p2-p1| = absolute difference between two proportions; n1: Sample size for group #1; n2: Sample size for group #2; α: Probability of type I error; β: Probability of type II error; z: Critical Z value for a given α or β; K: Ratio of sample size for group #2 to group #1.

Figure 2 Body proportionality assessment, ectodermal and myopathic sign assessment in persons with musculoskeletal reinjuries. A: Body proportionality assessment; B: Ectodermal and myopathic sign assessment. ^aP < 0.05, the differences are significant; ^bP < 0.001, the differences are highly significant.

Figure 3 Assessment of osteoarticular dysplasia signs and internal dysplasia signs in persons with musculoskeletal reinjuries. A: Assessment of osteoarticular dysplasia signs; B: Assessment of internal dysplasia signs. ^aP < 0.05, the differences are significant; ^bP < 0.001, the differences are highly significant.
