Abstract:Objective: To explore the applications of landmarking method and joint modeling for dynamic risk prediction in the analysis of longitudinal dataset obtained from real-world study. Methods: Based on the longitudinal prognosis data of 358 pneumonia patients, we used landmarking method and joint modeling respectively by software R, to estimate the probability of survival for the pneumonia patients who are under observation on day 5, day 10, and day 15. Results: Both of the two methods can make dynamic risk predictions on the probability of outcome in the future at different time points. On day 5, day 10, and day 15, the AUCs of the prediction using landmarking methods were 81.64%, 85.89%, and 82.15%, respectively, while those obtained from the joint modeling were 81.11%, 85.07%, and 72.09%, respectively. Conclusions: In the real-world study for dynamic historical data, dynamic prediction model analysis can be used to obtain more information. |
