a
‘Sedentary' is defined as ‘performing less than 150 min of moderate intensity physical activity per week'.
b
Standard management of patients with bilateral orchiectomy includes testosterone substitution, but none of the patients included in this study had testosterone levels outside of the normal range at the point of inclusion.
