  • Note:—CF indicates contrast filling; NF, no filling; PTA, percutaneous transluminal angioplasty.
  • ↵a Data are expressed as mean ± SD (range) or number of cases (% of cases).
  • ↵b P values were estimated using the Welch t test between CF and NF groups.
  • ↵c P values were estimated using Fisher exact tests or χ2 tests between CF and NF groups.
