Average nociception level (index; A), bispectral index (B), heart rate (HR; C), and mean arterial pressure (MAP; D) values observed at baseline (awake), loss of consciousness, intubation, end of anesthesia, and eyes open. Data are given for the total population (blue symbols), nociception level–guided (orange squares), and standard clinical care (dark red squares). Comparisons shown are for the total population. Values are mean ± 95% CI.
