  1. IQR: Interqualtin range; No→No: no risk of ED in either preadolescence or adolescence; Yes→No: risk in preadolescence but no risk in adolescence;
  2. No→Yes: no risk in preadolescence but risk in adolescence; Yes→Yes: risk in both preadolescence and adolescence; V/V: Val/Val; V/M: Val/Met;
  3. M/M: Met/Met. No significant differences between V/V and V/M + M/M genotypes in either group
