Independent variables reported are those that remained in the model after stepwise backward elimination analysis and were statistically significant in the final model (p<0.05). Independent variables were chosen on the basis of significant univariate associations and pathophysiological mechanisms. R2 of the final model was 0.0347 for ADMA, 0.0179 for L-arginine, 0.0247 for the Arg/ADMA ratio.
BMI denotes body mass index. eGFR denotes estimated glomerular filtration rate.
