Fig. 6. Cosinor parameter of the midline estimating statistic of rhythm (MESOR) of rest–activity on the 5 days after anesthesia (D1, D2, D3, D4, D5) for the three Zeitgeber times (ZT) of propofolanesthesia or Intralipid administration (  A–C ). Baseline represents values of rest–activity MESOR 5 days before propofol administration taken as 100%.  Error bars represent SEM. * Significant differences (  P < 0.05) from mean values in preadministration period.
