  1. ESS = Epworth Sleepiness scale, PROMIS = patient-reported outcomes measurement information system
  2. a. Correlations in bold are considered similar constructs, for which detailed hypotheses were created. The other correlations are of (somewhat) different constructs and are expected to be weaker than the bold font correlations for that PRAQ domain (for details, see Appendix 2).. Correlations for which we had no specific expectations are not shown
