Dv (10), Dv (50) and Dv (90) are the equivalent volume diameters at 10%, 50% and 90% cumulative volumes, respectively.
Span, [Dv (90) − Dv (10)] / Dv (50).
All values are mean±SD (n=3) and different superscript letters (^a-c) in the column indicate significant differences (p<0.05) by Duncan’s multiple range test.
