Logistic regression with stress fracture history as the dependent variable.
*p<0.05, **p<0.01.
†Eumenorrhoea as the reference group.
CET, Compulsive Exercise test; EDE-Q, Eating Disorder Examination-Questionnaire. The global CET and EDEQ variables represent a comparison with a median split. Models are adjusted for weight (kg), and training duration (hours/week).
