Figure 2 Relationship Between BNP Quartiles and In-Hospital Mortality
In-hospital mortality rates by B-type natriuretic peptide (BNP) quartiles (Q) (unadjusted) in the entire patient cohort (A), in patients with left ventricular ejection fraction (LVEF) <40% (n = 19,544) (B), in patients with LVEF  40% (n = 18,164) (C), and in patients with LVEF 50% (n = 12,631) (D). Each among-group comparison p < 0.0001.

Figure 3 Scatterplot Smoother of BNP Levels and In-Hospital Mortality
Local regression scatterplot smoother (loess) of B-type natriuretic peptide (BNP) levels and in-hospital mortality risk. The vertical marks on the loess line indicate density of the data.
