ESR1 and hypertensive disorder: As demonstrated in Table 1, significant differences were found in age (p = 0.0003), complicated hypertension (p = 0.0006), CRP (p = 0.002), NEU (P = 0.0002), LYM (p = 0.0006), MONO (p = 0.0009), HGB (p = 0.0007), PLT (p = 0.0003), ESR (p = 0.0004), ALB (p = 0.0005) in the training set, while most indicators in validation and testing set had no difference (Supplementary Tables 1, 2).
