Table 2. Reliability of measurement.

Intraclass correlation coefficients for each of measured variables associated with condition stimuli (placebo, nocebo, control) or control stimuli.

^a Condition refers to stimuli that were associated with placebo (placebo group), nocebo (nocebo group) or control (control group).

^b Control refers to stimuli that served as control stimuli in each of the group.

^c Intraclass correlation coefficient.

^d Confidence intervals.
