  1. *Each interaction is examined in a separate analysis including the main effects of sex, age, brachial baseline diameter, FMD, and the reactivity/recovery measure in question, but the main effects are not presented in the Table.
  2. **Calculated for the whole model.
  3. ***Refers to the interaction term.
  4. HR = heart rate (bpm); RSA = respiratory sinus arrhythmia (log ms2); PEP = pre-ejection period (ms); FMD = flow-mediated dilatation (%).
