Predictors for relapses - coefficient of determination in weighted regression models.

Coefficient estimates and coefficient of determination (adjusted R2) of univariate regression models of baseline variables and outcomes. R2 is the proportion of variability in the data that is accounted for by univariate regression model. Variables were also analysed for their change over time (variables vs. start date). Significant (p<0.05 (*)) correlations were used for the multivariate modelling. RRF  =  Rate of relapse free patients after 2 years, ARR  =  Annualized relapse rate over 2 years.
