Safety and efficacy of frequency-domain optical coherence tomography in evaluating and treating intermediate coronary lesions

Table 3 Frequency-domain optical coherence tomography findings in the percutaneous coronary intervention and optimal medical therapy groups

Variable	OCT-guided PCI (n = 38)	OCT-guided OMT (n = 26)	P-value
Reference area mm2	9.00 (7.56-11.21)	9.32 (7.73-12.14)	0.507
Minimum luminal area mm2	2.44 (1.93-3.15)	3.43 (2.61-4.72)	0.001
Area stenosis %	72.22 ± 7.39	61.87 ± 7.51	< 0.001

Data are expressed as mean ± SD and n (%), or median and 25^th and 75^th. Percentiles for non-normal distribution. OCT: Optical coherence tomography; PCI: Percutaneous coronary intervention; OMT: Optimal medical therapy.
