Renin Trajectories and Outcome in Stable Heart Failure with Reduced Ejection Fraction (HFrEF) on Contemporary Therapy: A Monocentric Study from an Austrian Tertiary Hospital Outpatient Clinic

Figure 2

Baseline renin distribution and association of renin with HF severity and HF medication. (a) The association of renin with HF severity reflected by NT-proBNP levels and NYHA class is visualized for individual values as a scatter plot and Tukey’s boxplots. The Spearman correlation coefficient for the former and level of significance are indicated. (b) Comparison of renin levels between different patients with any, with different, or without HF-specific medications. Individual values are shown alongside Tukey’s boxplots. For all comparisons, nonparametrical tests (Mann–Whitney and Kruskal Wallis) were used. were regarded as significant.
