To determine the ratio of Zn to TMP that is most effective in treating viral influenza infection (10 EID50). Fertilised chicken eggs (n = 12) were infected with data shown with solid line connecting each data point. From (a) and (d) it seemed that the peak of survivors reached at Zn/TMP ratio of 0.18. However by analysing the data closely in (b) and (c) it appeared that the reliable Zn/TMP ratio is 0.15. (a) Data are displayed as solid points. (b) Polynomial equation (Y = 65.603867 − 41.570169 × X − 3474.1479 × (X − 0.155)2 + 1821.6868 × (X − 0.155)3) was applied and mean (solid line) 1 and 2 standard deviations (dotted lines) were plotted. c Area analysis with colour variation whereby orange-red represent consistent data. d same plot as a with data points joined by solid lines
