  1. Footnote: TM = Tactile massage, RTM = Rest to music. AUCG = area under curve from ground level.
  2. Statistical methods used; Mann–Whitney-U, Chi-2-test, Median test and Kruskal-Wallis test. There were no statistical differences between groups. Eight time intervals < 60 min. at 8th intervention and once at first intervention. §This patient had concentrations, 7.7, 9.7, and 10.2 nmol/L, excluding a cortisol arousal reaction (CAR).
