Answer 1

You can do calculations for other years using the formulas. I have shown the calculation for one year.

1 (x) Year after Diagnosis 12(Ix) 13 (dx) | 4 (Wx) | 5 (R) Alive at Died Withdrew Effective beginning during during number exposed to of year year year Risk of during year 1 6(ax) Proportion who died. during 17(px) 18 (14) Proportion Cumulative proportion who did not who survived from die during enroll to end of 1 year 1st year TO D 0.18 0.82 0.82 - 2nd year 4 40.5 0.148 10.852 0.698 + 20 ирж | 32 10.063 0.937 0.654 4th year sy 25.5 10.039 0.961 0.629 20.5 10.097 10.903 22 0.568 w 5th year

• Effective no, exposed to Risk of dying =/No. alive during year at beginning of year / No. withdrew during year 2 For 1st year, ( v 50 Effective no, exposed to Risk of dying =( during year (R2) . Proportion who died during year (9x) = Mumber died Effective no expesed to Risk during year of dying during year For first year, ax = dx/Rx = 9/56= 0.18 Proportion who did not died during year (px) = l- qr. For first year, x = (1-0.18)= 0.82 Cumulative proportion who survived from enroll to to the end of year - Product of annual survival rates for the given year a all preceding years. For 5th year, Pu=(0.820.872x0.937X0.961 80.903) -0.308
