FIGURE 5.

Forest plots of the standardized regression coefficient estimate for associations between motor unit characteristics and contraction levels in males and females models. Beta value and 95% confidence intervals (CI) represent the standardized model predicted change per unit from 10% to 25% maximum voluntary contraction (MVC). All statistical analysis was based on multilevel mixed effect linear regression models with each subject as an independent cluster. Standardized values of each parameter make the comparisons executable between men and women. ^‡ P < .001
