  2. Sensitivity analysis ii: The results of unweighted multivariate logistic regression
  3. Ln means ln-transformed organochlorine pesticide
  4. The model was adjusted for age, ethnicity, education level, marital status, BMI level, and PIR smoking status,
  5. alcohol usage, menarche age, ever been pregnant, oophorectomy, and ever taken birth control pills
  6. The bold values mean statistical significance
