>"Vitamin C treatment significantly reduced tumor growth compared to vehicle control treatment (Fig. 2B)." This is a perfect example of what is wrong with biomed research. Just because the null hypothesis of no difference is rejected does not mean it is for your favorite reason. There are other reasons for this difference. For example, as mentioned above, perhaps the initial tumor size was different (which we cannot see since the size of the points in figure 2 correspond to ~50 mm^3 on the y axis).
