Kozinszky and Bartai (A-27) examined contraceptive use by teenage girls requesting abortion in Szeged, Hungary. Subjects were classified as younger than 20 years old or 20 years old or older. Of the younger than 20-year-old women, 146 requested an abortion. Of the older group, 1054 requested an abortion. A control group consisted of visitors to the family planning center who did not request an abortion or persons accompanying women who requested an abortion. In the control group, there were 147 women under 20 years of age and 1053 who were 20 years or older. One of the outcome variables of interest was knowledge of emergency contraception. The researchers report that,

ð Þ OR ¼ .07 than the relevant knowledge of the teenage controls OR ð Þ ¼ .10 .” Explain the meaning of the reported statistics. What are your conclusions based on the given information?
