Fig. 4From: Development of superior chitosan–EDTA microparticles as an adsorbent base for solidifying the self-emulsifying drug delivery systemsPareto charts for SE-CHEM A practical yield, B zeta potential and C particle size. ZP show that both CH and DT have a positive effect on it. It is clear from parameter estimates that the CH × DT interaction significantly contributes to the regression model for smaller particle size (PS). CH and DT have a negative effect on PSBack to article page
