Pathology | Predictor | B coefficient | Odds ratio (95% confidence interval) | p value |
---|---|---|---|---|
Pilocytic astrocytoma | ADC 10th percentile | 0.013 | 1.013 (1.002–1.025) | 0.022 |
Intercept | −15.887 | 0.021 | ||
Medulloblastoma | ADC 10th percentile | −0.014 | 0.986 (0.977–0.996) | 0.004 |
Intercept | 9.269 | 0.003 | ||
The reference category is ependymoma. |
ADC: apparent diffusion coefficient. In stepwise multivariable multinominal regression analysis for differentiation of fourth-ventricular medulloblastoma, pilocytic astrocytoma, and ependymoma (n = 51), ADC 10th percentile value was the only independent predictor (p < 0.001 for whole regression model).
