Screening interval 3 years and 5 years
Have created markov model for annual screening of population with life time horizon using different screening strategies Vs no screening and annual transition probabilities for each stage of the disease. Have used currentage=start_age+_stage in the model, stages=70 since its life time horizon and starting age as 35 years for age group 35-40 years, 40 years for age group 40-45 years, 45 years for age group 45-50 years etc.
Now would like to do analysis for screening interval 3 years and 5 years with life time horizon instead of annual screening. Kindly guide how to do this.
