Table 2.
Comparison of the Persistent & Transient Models: Goodness of Fit of Overall Model & Multiple R2 for Platelet Outcomes.
| Goodness of Fit Statistics | Persistent Model | Transient Model |
|---|---|---|
| AIC | 226.27 | 345.73 |
| CFI | 0.973 | 0.830 |
| Variance in Platelet Outcomes Accounted for by the Model, R2 | ||
| P-Selectin Variable | Persistent Model | Transient Model |
| Y1 Reactivity | 90% | 53% |
| Y2 Reactivity | 64% | 41% |
| Y3 Reactivity | 62% | 59% |
| Y1 Recovery | 70% | 39% |
| Y2 Recovery | 57% | 22% |
| Y3 Recovery | 33% | 40% |
Note: AIC = Akaike’s Information Criterion; lower values indicate better model fit (Akaike, 1974). CFI = Yuan-Bentler Corrected Comparative Fit Index; values above 0.95 are generally considered to exhibit good fit (Bentler and Yuan, 1999, Hu and Bentler, 1999). Y1 = Year 1, Y2= Year 2, Y3 = Year 3.
