Table 2. Sex ratio of survivors treated with potentially high-dose gonadal irradiation vs those treated with presumed low-dose gonadal irradiation, based on pooling of data from the current study, that of Winther et al (2003) and that of Byrne et al (1998)

  Boys/girls ratio among survivors treated with  
Sex survivor High gonadal dose Low gonadal dose ORa (95% CI)
Males1.01 (272/269)b 1.02 (1773/1742)b 0.99 (0.83, 1.19)
Females0.97 (308/318)b 1.06 (2570/2433)b 0.92 (0.78, 1.08)

 CI=confidence interval; OR=odds ratio.
