Figure 2: The nomogram predicts 1, 2, and 5year survival probabilities and median survival time (months). To use the nomogram, draw a straight line upward from the patient's characteristics of the frontal tumor, cerebellar tumor, the extent of resection, radiotherapy to the upper points scale, and the sums of the scores of all variables. Then, draw another straight line down from the scale of the total points through the 1, 2, 5year, and median survival time. This is the probability of the presence of prognosis in an individual
