Table 2.

Calculation for probability values (P-values) in Decision tree II. The P-values were given with 2 decimals. Since the sum outcome P-values in each treatment group need to equal 1, some adjustments needed to be made. Since with rounding to 2 decimals and with the condition that no P < 0.01, the sum of the rounded P-values was 0.03 too high. To avoid this, 0.01 was taken from the rounded P-values that were higher than 0.01.
