Comparisons between Different State Anxiety Score Groups with the RE and SE during Induction and LOC, and Concentration of Effective Site

Data are number or median (interquartile range). Stratified into three groups based on their anxiety scores: Low group (< 25% STAI scores), Middle group (25%-75% STAI scores), High group (> 75% STAI score). STAI: Spielberger State-Trait Anxiety Inventory, STAI-X1: STAI scale for state anxiety, RE: Response Entropy, SE: State Entropy, Ce: effect-site concentration, LOC: loss of consciousness. ^*P < 0.05 when compared with low group under Bonferroni correction (adjusted P = 0.027).
