did not reach statistical significanceP = 0.2687
The increase of the number of different haplotypes was significant in the evolution from Group HCV p0 to Group HCV p100 ( P = 0.0439; t test) and from Group HCV p0 to Group HCV p200 ( P = 0.0015; t test), while the difference between Group HCV p100 and Group HCV p200 did not reach statistical significance ( P = 0.2687; t test).
