Viktoras had nothing to do with the study and doubtfully ever worked for him.
The study says a lot of things that 100g comparable dosages in humans have a five fold decrease of cancer and then a bunch of other comparisons.
I hardly think it's reliable at all. However, the flip side of your point is that they did say that a diet of raw food caused the same decrease as the high 100g dosage.
The big but is:
When used together, the raw fruits and vegetables and vitamin C caused a remarkable 35-fold decrease in cancer incidence.
So with the addition of Vitamin C raw food went from a 5 fold decrease in cancer to 35 fold decrease.
What that says very clearly is that vitamin c caused a huge decrease far above what raw foods could do alone.
