84.2 (SD = 17.6) for the control group, resulting in an estimated β of 2.54 (95% CI = –4.46 to 9.54; P = 0.47) for the effect of the intervention (Table 2). Dichotomised scores. Between the two groups, 18.8% of patients in the OPT group had low empowerment compared with 24.1% in the control group, but the difference was not statistically significant (OR 0.73; 95% CI = 0.28 to 1.86; P = 0.50). Two patients scored very low empowerment in the control group and no patients scored very low empowerment in the OPT group. Table 1.
