    The minor (80-50) and the major (qy); Re: More accurately?

    Dear Editor

    Vlassov[1] detected something wrong in my short piece.[2] I would like to thank him very much. The correct lines 2 and 3 of paragraph 2 are: DALYs=(0.33)x(50y)+(1.0)x(80y-50y)=46.5y.

    However, this is the minor, I think: the reader can easily understand or infer that printer's devil has replaced a 5 with a 3.

    We read the Letter by Dimoliatis with interest.[1] However, "0.33x50+1.0x(80–50) = 46.5", more accurately, we had to put QALYs = (0.67)x(50y) = 33.5y and DALYs = (0.33)x(50y)+(1.0)x(80y–30y) = 46.5y.

    If substitute (80-50) by (80-30) result must be different.

    I believe that something is wrong in this short piece intended to add clarity!
