NYHA class
SF-36 scalesIa (n=24)IIb (n=98)IIIc (n=83)Totald (n=205)Dialysis (n=120)Hepatitis (n=70)Major depression (n=502)Normal (n=906)
Significance (a,b,c,d ): p<0.05 by t tests between groups with the designated letters and NYHA I (a), NYHA II (b), NYHA III (c), and entire heart failure population (d). To control for the multiplicity problem of multiple comparisons, only adjusted p values are reported (after Bonferoni <0.00156).
