TABLE 4.
Results of the linear models in which each risk score was used as the outcome (dependent variable) and categorization of the fitness status as the predictor, adjusting for covariates. Estimates can be interpreted as the increase in the percentage risk score for individual in the NORMAL and UNFIT categories compared to the FIT (reference) group.
