They found the average improvement for the SMC group over baseline was 0.02 QALYs. This is based on taking measurements from a few points. Basically if one had a graph with a line across at y=0.48, one marks in the values in table 3, join the dots using straight lines (they say that as far as I recall), calculate the area above the y=0.48 line and get the average value over the 52 weeks and that is the QALYs accrued.
So do you mean that there should be an ICER cost per QALY for SMC?
