  • * All RR estimates and 95% CIs are based on the matched evaluation and are adjusted for highest professional degree and self-reported height 1 year before interview.

  • Based on all food items containing galactose (soft cheese, cheese, yoghurt, milk, low-fat milk, cacao, butter, and cream).

  • RR estimates and 95% CIs are based on the matched evaluation and are adjusted for highest professional degree, self-reported height 1 year before interview, history of familial testicular cancer, and history of cryptorchidism.
