Independent association of the discrepancy between 3D QCA and IVUS/OCT long diameter with vessel curvature and catheter looseness
| IVUS—3D QCA | OCT—3D QCA | |||
|---|---|---|---|---|
| βa (95% CI) | P | βa (95% CI) | P | |
| Vessel curvature | 5.32 (0.80–9.85) | 0.02 | 4.63 (0.66–8.59) | 0.02 |
| Catheter looseness | 0.20 (0.04–0.37) | 0.02 | 0.14(0.10–0.26) | 0.04 |
aMultiple linear regression adjusted for catheter looseness and vessel curvature. β indicates unstandardized β coefficient. CI Confidence interval; n = 40 vessels from 37 patients
