  1. Abbreviations: CI=confidence interval; Cis=cisplatin; FSH=follicle stimulating hormone; RT=radiotherapy.
  2. aOn the basis of linear regression analyses, the analysis was performed on the logarithmic value of s-FSH; numbers stated as % are the exponentially transformed regression co-efficients.
  3. bOn the basis of tobit censored linear regression, the regression co-efficient corresponds to change in absolute values of s-inhibin B (ng l−1).
