Values are n (%) or mean ± SD (range). N = 254 patients and 484 for vessels.

FFR = fractional flow reserve; FFRCT = fractional flow reserve derived from standard acquired coronary computed tomography angiography datasets; ICA = invasive coronary angiography; other abbreviation as in Table 2.

  • Agatston score was measured in 214 patients.
