M1—Model 1 regressions featured demographic variables individually.
M2—Model 2 added SBP, for SBPV, and DBP, for DBPV, as predictors (No model 2 was run for SBP, and DBP, as outcomes).
M3—Model 3 regressions featured all demographic predictors jointly, as well as the corresponding BP, variable for BPV, and 3 additional binary covariates (Health condition, medication use, smoking status).
Means and SEs, are presented for each level of the predictors, as well as p-values for each predictor’s overall effect.
The bold value means significant at < 0.05.
