1Pearson’s chi-square test. 2Pearson’s chi-square test after Bonferroni’s correction. 3Odds ratios were calculated with Haldane’s modification, which adds 0.5 to all cells to accommodate possible zero counts. 4Calculated according to Sheskin, 2004. 5Calculated by logistic regression. The OR were corrected by age, smoking, contraceptive methods and number of sexual partners. NA (not available) depicts variables for which calculation of logistic regression is not possible due to the existence of zero counts in one or more categories.
