Linear Regression Analysis of Retention Vs. Myocardial Blood Flow for Low and High Flow Ranges
Group Flow range Low (≤1.0 mL/g/min) High (>1.0 mL/g/min) Group 1 Sestamibi slope 0.3070 ± 0.01028 (<0.0001) 0.1738 ± 0.006233 (<0.0001) Tetrofosmin slope 0.05974 ± 0.009525 (<0.0001) 0.005058 ± 0.005291 (0.3412) Are the slopes different? (P) <0.0001 <0.0001 Group 2 Sestamibi slope 0.3670 ± 0.01326 (<0.0001) 0.08652 ± 0.003768 (<0.0001) Q12 slope 0.02401 ± 0.006020 (<0.0001) 0.01223 ± 0.001190 (<0.0001) Are the slopes different? (P) <0.0001 0.05571 Values in parentheses indicate probability values testing presence of slope different from 0 for relationship between retention and flow.
