Data are RRRs (95% CI); Model 1 was adjusted for age, sex, BMI, eGFR, and urinary creatinine; Model 2 was additionally adjusted for physical activity level and smoking. Multinomial logistic regression models were used (Q1 was considered as reference category).
HTN phenotypes were defined as: ISH (SBP ≥ 130 and DBP < 80 mmHg), IDH (SBP < 130 and DBP ≥ 80 mmHg), and SDH (SBP ≥ 130 and DBP ≥ 80 mmHg).
UNa-K ratio: Q1 < 1.23, 1.23 ≤ Q2–Q4 < 3.14, Q5 ≥ 3.14.
Median of UNa-K ratio was 0.91, 2.01, and 4.05 in Q1, Q2–Q4, and Q5, respectively.
HTN hypertension, ISH isolated systolic hypertension, IDH isolated diastolic hypertension, SDH combined systolic and diastolic hypertension.
