Fig. 4From: Relationship between pre- and post-operative isokinetic strength after ACL reconstruction using hamstring autograftThe graph illustrates the scatter plot, regression line and regression equation for the relationship between the dependent variables maximal isokinetic knee extension (left) and flexion torques (right) normalized to body mass of the injured leg obtained before (abscissa) and after (ordinate) ACL reconstruction. R2 linear is the coefficient of determination; the fitted regression line is described by the equitation yBack to article page
