near significancep=0.065
Statistically, this abundance was significant for the L2 haplogroup (p=0.008) and near significance for the T haplogroup (p=0.065).
Statistically, this abundance was significant for the L2 haplogroup (p=0.008) and near significance for the T haplogroup (p=0.065).
Pair-wise exact tests between cohorts showed that this statistical heterogeneity is mainly due to particular differences between PEG versus HMC (p=0.016) and PEG versus HSA group (p=0.027) as haplogroup differences between both control groups did not reach statistical significance (p=0.178). χ 2 or two tailed Fisher exact tests analysis of haplogroup frequencies in PEG patients versus HMC group indicate that haplogroups T and L2 were in significant excess in PEG patients compared to HMC (p=0.025 and p=0.045, respectively).
