Table 5 Results of multilinear regression analysis to identify factors associated with caregiver’s CarerQoL and EQ-5D-5L utility scores, respectively

From: Factors associated with care- and health-related quality of life of caregivers of children with juvenile idiopathic arthritis

 

CarerQoL

EQ-5D-5L (two-part model)

 

OLS regression with robust standard errors results

Logistic regression model for probability of reaching full health score (EQ-5D-5L = 1)

OLS regression results for caregivers with EQ-5D-5L utility scores less than 1
