Multivariable models of molecular oligodendroglioma status based on tumor circumscription and ADC valuea
| Odds Ratio | 95% CI | P Value | |
|---|---|---|---|
| Model A | |||
| Circumscribed | |||
| Partial/yes | Reference | ||
| No | 5.24 | 1.27–24.42 | .02 |
| Overall mean ADC, 0.5 decrease | 5.66 | 1.53–27.49 | .02 |
| Model B | |||
| Circumscribed | |||
| Partial/yes | Reference | ||
| No | 5.55 | 1.40–24.99 | .02 |
| Mean min ADC, 0.5 decrease | 2.75 | 0.78–11.36 | .13 |
| Model C | |||
| Circumscribed | |||
| Partial/yes | Reference | ||
| No | 7.09 | 1.81–33.83 | .007 |
| Mean max ADC, 0.5 decrease | 3.89 | 1.45–12.58 | .01 |
↵a Model A indicates mean ADC (C statistic = 0.80); Model B, minimum ADC (C statistic = 0.74); and Model C, maximum ADC (C statistic = 0.81).
