Flawed Data Presenation Confusing Data presented by Management. They need to group the patients samples based on the number of days after the treatment ( eliminate the pending column) For instance If 25 patients have completed 180 days, they should take only 25 as total population to arrive at effective percentages. Again, if 12 patients have finished 360 Days, they should only use 12 as the total population. Progressively, If only 4 patients have completed 450 days, they should use only 4 patients as total population and then arrive at the effective percentages. Otherwise, it is statistically flawed and confusing. IMHO
