Scatterplot showing individual AAI and BIS at different OAA/S scores during the onset and recovery phases of propofol-induced sedation. The linear regression lines were analysed. AAI=17.60(OAA/S score)–3.62; BIS=6.18(OAA/S score)+65.83; n=90, during the onset phase. AAI=18.61(OAA/S score)–8.97; BIS=3.68(OAA/S score)+76.02; n=72, during the recovery phase.

Scatterplot showing individual AAI and BIS at different OAA/S scores during the onset and recovery phases of midazolam-induced sedation. The linear regression lines were analysed. AAI=17.91(OAA/S score)–5.03; BIS=12.25(OAA/S score)+38.96; n=70, during the onset phase.
