Fig. 5. Cosinor parameter of the amplitude of body temperature rhythm during the 5 days after anesthesia (D1, D2, D3, D4, D5) for the three Zeitgeber times (ZTs) of propofol anesthesia or Intralipid administration (  A–C ). Baseline represents values of rest–activity amplitude 5 days before propofol administration taken as 100%.  Error bars represent SEM. * Significant differences (  P < 0.05) from mean values in preadministration period.
