Sketch the QALY diagram and determine how many QALYs are achieved during the year by a patient in a 1-year clinical trial who has a baseline EQ-5D health state of 13322, a 6-month EQ-5D health state of 12212, and a 1-year EQ-5D health state of 11211. Assume that health states changes between measurements are smooth and gradual over time so that changes in utility scores can be approximated by a straight line.

According to the baseline EQ-5D health state table, 13322 has value (0,370), SE (0,014)

@ 6 Months 12212 has value (0,765) , SE (0.009)

@ 12 Months 11211 has value (0,880), SE (0.008)
