CIL, pre-intervention data sets, mm	68.6 ± 17.3 (n = 50)
CIL, post-intervention data sets, mm	69.0 ± 19.5 (n = 93)
CIL, pre-intervention data sets from arteries with a proximal reference diameter ≥3.5 mm, mm	67.5 ± 17.4 (n = 30)
CIL, pre-intervention data sets including severe stenosis with MLA <0.63 mm2, mm	60.7 ± 6.8 (n = 5)
CIL, pre-intervention data set subsegments distal to the MLA location	>90% in 88% of the acquisitions (n = 50)

Values are mean ± SD unless otherwise indicated.

CIL, clear image length; HF-OCT, high-frequency optical coherence tomography; MLA, minimum lumen area.
