Abstract S35 Table Multiple linear regression analysis of QMVC (dependent variable, n  =  239)
Coefficient (95% CI)p Value
Sex (F–M)−8.7 (−12.0 to −5.3)<0.001
Weight (kg)+0.2 (0.1 to 0.3)0.001
Height (m)+14.9 (−2.4 to 32.2)0.09
Age (years)−0.4 (−0.5 to −0.3)<0.001

  • Model r2  =  0.47. Regression coefficients (95% CI) describe the change in maximum voluntary quadriceps contraction strength (QMVC) per unit change in the group or covariable.
