A two-way ANOVA conducted across both cell lines demonstrated a highly significant main effect of drug concentration (F(1,80) = 199.32, p < 1.99e − 23), a significant interaction between formulation and concentration (F(3,80) = 8.01, p < 9.89e − 05), and a significant main effect of formulation type (F(3,80) = 4.08, p = 0.0095), indicating that cytotoxicity is concentration-dependent and formulation-specific, with more pronounced differences observed at higher doses.
