Table 3. Multivariable Analysis of Patient-Reported Factors Associated With HF-Specific Health Status Over One Year.

Variables Adjusted R2a KCCQ Score
Estimate Standard Error P-value
Overall model 0.21 <0.001

 Chest pain 0.05 −2.02 0.70 0.004
 Numbness/tingling −1.15 0.57 0.045

HF = heart failure; KCCQ = Kansas City Cardiomyopathy Questionnaire; PHQ-9 = Patient Health Questionnairee−9.

a

The individual adjusted R-squared values do not add up to the overall model R-squared. This is an expected result of correlation between the factors.

b

Depressive symptoms estimate is per five-point increase in PHQ-9 score.
