Students’ t-test or Mann-Whitney U test were used to compare continuous variables. Logistic regression is used to assess whether variables are independent predictors. A p-value less than 0.05 was considered statistically significant. Statistical analysis was performed using R 4.2.3 software....
Six prevalentG6PDmutations were selected for correlation analysis with both G6PD activity and G6PD/6PGD ratio. It was found that different gene mutations had various levels of G6PD enzymatic activities (Fig.1and Table2). The second most common allele of c.1376 G > T (p.R459L) had ...
