Partial Least Square Determinant Analysis (PLS-DA) model for all dog unstimulated saliva samples SDS-PAGE bands [Δ: Portuguese Podengo (n = 7); +: Greyhound (n = 11); ◊: Rafeiro Alentejano (n = 13); and x: Beagles (n = 10)] (a) and for stimulated saliva samples SDS-PAGE bands [+: Portuguese Podengo (n = 6) and Δ: Beagles (n = 8)] (b). Scaling was applied to rows when needed; X and Y axes show principal component 1 (PC1) and principal component 2 (PC2), respectively, and the contribution of each of them for explaining the total variance.
