  1. Ndet: number of detectors. 1 = 16, 2 = 40, 3 = 16/64, 4 = 64
  2. Brand: 1 = Siemens, 2 = GE, 3 = Philips, 4 = Toshiba
  3. Kernel: 1 = B20-30f, 2 = B46f, 3 = B46, f + filter, 4 = combination
  4. CT/PCI: average number of months between scan and stent placement
  5. NAP: Non-assessable proportion of stents
  6. StrTh: Strut Thickness. 0 = no data, 1 = Str Th < 100 μm, 2 = Str Th > 100 μm
  7. EXC: non-assessable stents were excluded before analysis: 1, not excluded: 0
  8. Loc: Stent location in the coronary. Left main or not specified = 1, other = 2
  9. Size: average stent diameter in mm
  10. Kv: kilovoltage
