Rpsft method
Webderived using the RPSFT method. Within these CE models, results of a probabilistic sensitivity analysis (PSA) are required to be presented alongside the deterministic outcomes. PSA is utilized to present the likelihood of an intervention being considered cost-effective by incorporating uncertainty around a range of model inputs. WebThe RPSFT method maintains the original randomized group definitions and thus preserves the validity of between-group comparisons by providing a randomization-based estimate of treatment effect corrected for the bias introduced by crossover. This approach is expected to project survival estimates for patients in the control arm to mirror ...
