Table 4 Percentage of patients with accessible coronary segments, stratified from proximal to distal portions of the coronary tree

	All patients (n = 242)	Group 1 (n = 116)	Group 2 (n = 126)	P value (*)
Patients with 4 segments accessible	162 (67%)	73 (63%)	89 (71%)	0.20^χ
Patients with 7 segments accessible	55 (23%)	25 (21.5%)	30 (24%)	0.67^χ
Patients with 10 segments accessible	7 (3%)	2 (2%)	5 (4%)	0.45*
Patients with 15 segments accessible	0	0	0	NA

NA: not applicable
Comparisons between group 1 and 2 were obtained with chi-square test (^χ) or Fisher’s exact test (*). No significant difference in the percentage of patients with four, seven, and ten accessible segments was observed between the two patient groups
