From: Mis-anaesthetized society: expectancies and recreational use of ketamine in Taiwan
The distribution of the four combinations of binary positive and negative ketamine expectancies, i.e., High-Positive/Low-Negative (HpLn), High-Positive/High-Negative (HpHn), Low-Positive/Low-Negative (LpLn), and Low-Positive/High-Negative (LpHn), among the three groups of different ketamine-using experiences. The cutoff-points were the median of positive expectancies and negative expectancies, respectively, among those who were illicit drug-naïve (i.e., High-Positive as ≥1, High-Negative as ≥5). The vertical bar indicates the 95% confidence interval derived from RDS-weighted estimates
