Multiple linear regression and Pearson correlation for the relation between each measure of “advantage” and the “preference” for the alternative option over one stage TCPC (the dependent variable, DV)

Analysis: “main effect” of ...	R² for analysis	Predictor variables (IVs); difference in expected years	b (regression weight)	β (standardised weight)	Significance (p value for b/β)	Pearson’s r between IV and DV
For Pearson’s r, p<0.05, *p<0.01.
