Carlisle investigated the distribution of independent variables between study groups in Fujii's fraudulent research:
"The published distributions of 28/33 variables (85%) were inconsistent with the expected distributions, such that the likelihood of their occurring ranged from 1 in 25 to less than 1 in 1 000 000 000 000 000 000 000 000 000 000 000 (1 in 10³³), equivalent to p values of 0.04 to < 1 × 10^-33 , respectively."
