Note: Model was found to be statistically significant. Result of likelihood ratio test: χ² value - 281.549 and P value < 0.0001. CI indicates Confidence Interval. Base case includes patients who were in immediate treatment group, with race white, married, aged 80 or above, with moderately differentiated tumors and with greater than 1 comorbidities.
