Responsiveness of the CROQ (before to three months after revascularisation)
| CROQ scale | Mean (SD) score | Effect size† | ||
|---|---|---|---|---|
| Before | At 3 months | Change* | ||
| *All change scores are significant (p<0.05). | ||||
| †Calculated as mean change between pre- and three months post-revascularisation scores divided by the standard deviation of scores before revascularisation. | ||||
| ‡Subsample of patients who completed the CROQ both before and after coronary revascularisation. | ||||
| Note: It is not appropriate to compare CROQ scores for CABG and PTCA groups in this table, as this dataset has not been adjusted in terms of case mix severity, etc. | ||||
