Gender-Specific Differences on the Association of Hypertension with Subclinical Thyroid Dysfunction

Figure 1

Prevalence of hypertension in different age subgroups or different thyrotropin subgroups. (a) Age subgroups 1 to 7 are referred as follows: age < 25 years, 25 years ≤ age < 35 years, 35 years ≤ age < 45 years, 45 years ≤ age < 55 years, 55 years ≤ age < 65 years, 65 years < age ≤ 75 years, and age >75 years. Difference of prevalence between gender was significant at 0.01. (b) Thyrotropin subgroups 1 to 7 are referred as follows: TSH ≤ 0.3 mIU/L, 0.3 μlU/mL < TSH ≤ 1.0 μlU/mL, 1.0 μlU/mL < TSH ≤ 2.0 μlU/mL, 2.0 μlU/mL < TSH ≤ 3.0 μlU/mL, 3.0 μlU/mL < TSH ≤ 4.0 μlU/mL, 4.0 μlU/mL < TSH ≤ 5.0 μlU/mL, TSH > 5.0 mIU/L. Difference of prevalence between gender was significant at 0.01.
