How to interpret CEA results with different cycle length
I am conducting a cost-utility analysis, I have built a Markov model where the cycle length is 4 months. In the CEA results text report, my incremental effectiveness is 3.56 and my ICER is ~$31,000. How would you interpret this to present in a paper? Should I convert it to years?
The intervention provides an additional 3.56 quarter life-years? I assume to convert to years the calculation would be 3.56 x 4/12 = 0.89, so an additional 0.89 life-years? And then to get cost by year: $31000/0.89 = ~$35,000 per LY?
Your help and recommendations are appreciated!
