Svend A. Mortensen et al. JCHF 2014;2:641-649 Results of Subgroup Analyses Shown are the adjusted HR for the primary endpoint within specific subgroups. The dotted line denotes HR; horizontal lines represent 95% CI. HR indicates the relative risk in the coenzyme Q10 (CoQ10) group versus the placebo group within each stratum. To convert values for NT-proBNP to picomoles per liter, divide by 8.457. ACE = angiotensin-converting enzyme; ARB = angiotensin receptor blocker; NT-proBNP = N-terminal pro–B-type natriuretic peptide; NYHA = New York Heart Association; other abbreviations as in Figure 1.
