Changes in the Outcomes Between Study Groups Across Time Using Generalized Estimating Equation Model (N = 74)
pain
Group refers to the group differences at baseline between the intervention and control groups. Group*T1 refers to additional score changes of the variables in the intervention group compared with those in the control group at T1. Group*T2 refers to additional score changes of the variables in the intervention group compared with those in the control group at T2. T1 is close to the end of the clinical session (postintervention), and T2 is before transference to the operation theater (at ward) or after admission to operation theater (at the reception area).β refers to the group-by-time interaction terms and represents the difference in mean changes in an outcome at a specific time point with respect to the baseline (T0) between the intervention and control groups (mean change in intervention group minus mean change in control group).Changes in pain scores were also examined at T3 (after operation) between groups (T3, 62.86; 95% CI, 57.36 to 68.37;
