2. Fig 1
Measured ketamine concentrations (ng ml−1). Each filled circle represents one data point. Lines linking data points indicate which samples came from the same subject, and do not indicate estimated or extrapolated concentrations between samples.

3. Fig 2
Measured and predicted ketamine concentrations over time. Vertical bars represent the mean (sd) measured ketamine concentrations, but depicted at the average time (from the start of the infusions) at which the samples were obtained. Horizontal bars in the middle of the vertical bars represent the sd of the time interval at which the samples were obtained.
