Variable | OR (CI) | P value | Whole model AUC (CI) |
---|---|---|---|
ADC | 0.15 (0.01–0.65) | 0.007 | 0.89 (0.76–1.0) |
Maximum sizea | 3.9 (1.09–23.4) | 0.04 |
Log(maximum size) used to ensure normality assumption.
Odds ratios expressed are for standardized variables (calculated by subtracting the mean and dividing by the standard deviation). OR, odds ratio of upgrade vs. no upgrade; CI, 95% confidence interval; AUC, area under the ROC curve; ADC, apparent diffusion coefficient.
