Multiadjusted model: age, menopause, BMI, smoking, diabetes, antihypertensive medication, cholesterol lowering medication, contraception, income, unemployment, and education.
Correlation between TSH and TPOAb and number of children born and number of pregnancies are measured was by linear regression.
Association between TSH and TPOAb and spontaneous abortion (yes vs. no) was by logistic regression.
