Table 3 Multivariate logistic analysis for the factors associated with hypertension

From: Urinary sodium-to-potassium ratio associates with hypertension and current disease activity in patients with rheumatoid arthritis: a cross-sectional study

Variables OR 95% CI P value
Age (1 year) 1.09 1.08–1.13 <  0.001
Urinary Na/K ratio (1) 1.34 1.13–1.57 <  0.001
Sex (male = 1, female = 0) 1.56 0.70–3.47 0.27
Current smoking (+) 0.71 0.20–2.48 0.59
  1. Results of multivariate logistic regression regarding the presence of hypertension in RA patients. We constructed dummy variables as follows: 0 = without hypertension and 1 = with hypertension, and logistic analysis was carried out with potential confounders including age, sex, and current smoking status
  2. Abbreviations: RA rheumatoid arthritis, OR odds ratio
