For the simple regression analysis of PDGF β receptor tyrosyl phosphorylation: tyrosyl phosphorylation (arbitrary units) = intercept + (variable × β).
Intercept = 1.595; adjusted R2 = 0.317.
β, β coefficient for linear regression model; SE, standard error; Std coeff, standardised regression coefficient.
