 Responsiveness of the CROQ (before to three months after revascularisation)

CROQ scaleMean (SD) scoreEffect size†
BeforeAt 3 monthsChange*
*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.
