Data are presented as median (interquartile range) or n (%), unless otherwise indicated. “Glidesheath” denotes 7-Fr Glidesheath slender/7-Fr guiding catheter combination group, and “Sheathless” denotes 7.5-Fr sheathless guiding catheter group. The asterisk denotes a statistically significant difference between the two groups. CI, confidence interval; n/a, not applicable; OR, odds ratio.
