Figure 4 Percentage of Subjects With Detectable Assay Results

Bars represent the percentage of subjects in each group (see text) with measured levels above the minimal detectable concentration of each assay. Chi-square p values for between-group comparisons are given for each assay. ALVD = asymptomatic left ventricular dysfunction; BNP = B-type natriuretic peptide; CV = cardiovascular; HF = heart failure; MDC = minimal detectable concentration; NT = N-terminal.
