↵a P<.05.
↵b As these numbers are no longer on the scale of the regression, these values are specific to the type of subject the predictions were performed on (i.e., the values the other covariates are set at for prediction affect these numbers, unlike on the regression scale), which was the most common subject sex (female) and fasting value (true), median baseline age (54 years), and median years since diabetes diagnosis at baseline (4 years) for the subjects in analyses.
