  result_psa_params_treat = NULL,
  threshold = NULL,
  comparator = NULL
)

Arguments

result_psa_params_control	result from probabilistic sensitivity analysis for first or control model
result_psa_params_treat	result from probabilistic sensitivity analysis for the comparative Markov model
threshold	threshold value of WTP
comparator	the strategy to be compared with

Value

plot of sensitivity analysis
