TABLE 2. Age- specific fertility rates for subjects with or without a CRC diagnosis.

Age- specific fertility rates are given as births/ 1000 person- years. Total fertility rate (TFR) is given as births/ person. The sample sizes for subjects aged 15–19 with a CRC diagnosis were insufficient to calculate meaningful confidence intervals. Significantly different rates are marked in bold type.
