Protein spot contribution to discrimination between vastus lateralis and trapezius. PLS-DA weight plot (w*c/w*c) based on 545 protein spots. Situated on the left in the figure are protein spots characterizing the vastus lateralis muscle and on the right the trapezius muscle. Shaded area is proteins spots with variable of importance values (VIP) < 1. Protein spots significant according to the one way ANOVA and FDR correlated (◆). Protein spots significant according to one way ANOVA but not FDR correlated (◆). Protein spots not significant (○). PLS-DA model with two PLS-components ([t1],[t2]) represents 46% of the Y-variance ([t1], 27%, [t2] 19%).
