Rows correspond to different multivariate models whose outcome variable (dependent variable) can be found in the first column. Columns report the regression coefficients, standard errors, and Wald test p-value. Model 1 contains three covariates: age at the time of the blood draw. HIV status, and extrinsic epigenetic age acceleration.
