  • P values were obtained from McNemar’s test.

  • The overall total (1207) does not equal to the total (598+606=1204) at the lower half of the table because subjects who did not respond to the questions about (1) the number of sexual partners, (2) the method of contraception use at first and last sexual intercourse were not included in McNemar’s test.
