Note:—RFV4, RFV6, RFV8, RFV10, RFV12, RFV14, RFV16, RFV18, and RFV20 indicate intra-aneurysmal RFV with an average flow velocity of >4, 6, 8, 10, 12, 14, 16, 18, and 20 cm/s, respectively; and nRFV4, nRFV6, nRFV8, nRFV10, nRFV12, nRFV14, nRFV16, nRFV18, and nRFV20 indicate intra-aneurysmal nRFV with an average flow velocity of >4, 6, 8, 10, 12, 14, 16, 18, and 20 cm/s, respectively.
↵a Data are expressed as mean ± SD (range).
↵b P values were estimated using the Welch t test between CF and NF groups.
