| PICE | PICG | RES | POD | EDA | Vc | |
|---|---|---|---|---|---|---|
| Slop | 1.2535 | 0.4839 | 0.5018 | 0.1825 | 0.4548 | 1.2267 |
| Intercept | 23.779 | 14.191 | 14.599 | 13.273 | 14.615 | 20.764 |
| r | 0.9966 | 0.9998 | 0.9968 | 0.9973 | 0.9952 | 0.9966 |
| AAE | 1.022 | 0.394 | 0.409 | 0.149 | 0.371 | 1.000 |
AAE, namely, ascorbic acid equivalence, is the slope ratio calculated with Vc as reference.
