Figure 3. Nomograms to predict 1-year, 3- year and 5-year survival probability in osteosarcoma.

(A) Total points were obtained by incorporated the corresponding points of recurrence, metastasis, risk score on the point scale. The total points were then converted into specific 1 year, 3- yearand 5-year associated survival probabilities. (B) Calibration plot underlying the nomogram. Dashes show the nomogram-predicted probability for each group, as well as the respective confidence intervals.
