  1. The table gives information about at-home sleep parameters as assessed in our study (values are presented as M (SD); see also Table 3). Sleep as assessed in laboratory studies is reported for four studies (values are presented as M (SD)). Study 1: Achermann et al. [29]; Study 2: Arnal et al. [10]; Study 3: Curcio et al. [11]; Study 4: De Gennaro & Ferrara [30]. As effect size Cohen’s d is reported
  2. aIn these studies, descriptive data was given as M ± SEM, thus, SD was calculated by multiplying SEM by the square root of N (sample size)
