The data are presented as median (25th–75th centile) for continuous variables or as absolute number (%) for categorical data.
*P values were calculated using the Mann–Whitney U test and Fisher’s exact test for the difference between the small and large groups.
†Sheaths were not removed in one case in the small group and five cases in the large group. Results are shown for the remaining cases (52 in the small group, 20 in the large group and 3 in the unusual group).
PTA, percutaneous transluminal angioplasty; US, ultrasound.
