  • Multivariate models are adjusted for age, sex, high BP, diabetes, smoking status, and eGFR. The r2 statistics are not presented because the model for AAC is a zero-inflated negative binomial and does not allow r2 computation. The Akaike information criterion is presented as a similar measure of fit.
