marginally significantp = 0.06
Multiple regression analyses or multiple ordinal logistic regression analysis did not show significant interaction of ZnO-NPs exposure level and Nrf2 deletion for the above parameters, thus multiple regression model without the interaction was applied for them, although marginally significant interaction is noted for neutrophils ( p = 0.06) as it indicates different effect of ZnO-NP exposure level depending on the genotype.
