  1. BPV, blood pressure variability; SBPV, systolic blood pressure variability; DBPV, diastolic blood pressure variability; MBPV, mean blood pressure variability; OR, odds ratio; CI, confidence interval; HR, hazard ratio.
  2. *SBPV, DBPV, and MBPV as continuous variables are standardized (z-transformed). Model 1 adjusted for none;
  3. Model 2 adjusted for covariates included in demographics;
  4. Model 3 adjusted for Model 2 plus covariates included in vital signs and comorbidities; Model 4 adjusted for Model 3 plus covariates included in laboratory tests and treatments.
