Table 5 Association between ALT levels and hypertension prevalence among women

From: The association between serum alanine aminotransferase and hypertension: A national based cross-sectional analysis among over 21 million Chinese adults

ALT levels (U/L) Hypertensive, n (%) Age-adjusted OR (95% CI) Model I Model II
    Multi-adjusted OR (95% CI) Multi-adjusted OR (95% CI)
Group I     
0–40 257,764 (2.48) 1 1 1
40.01– 27,691 (4.64) 1.91 (1.88,1.93) 1.56 (1.54,1.58) 1.52 (1.50,1.54)
Group II

P for trend    < 0.001  < 0.001  < 0.001
  1. ALT: alanine aminotransferase; OR: odds ratios; CI: confidence interval
  2. Model I: Adjusted for age, sex, ethnicity, area, education, body mass index, average salt consumption, history of diabetes, overall pressure and hepatitis B surface antigen status
  3. Model II: add fasting blood glucose concentration as a new covariate based on Model I
  4. P for trend were calculated by setting categorized ALT levels as a continuous variable
