(1) Negative CTP-FFRCT match group (resting static CTP-negative and FFRCT-negative group); (2) mismatch CTP-FFRCT group (resting static CTP-positive and FFRCT-negative or resting static CTP-negative and FFRCT-positive group); (3) positive CTP-FFRCT match group (resting static CTP-positive and FFRCT-positive group).
*
The denominator is the number of patients in whom ICA was actually performed.
