Notes:

^***

Significance level at 99%.

^**

Significance level at 95%. Control variables were: age, sex, educational level, marital status and economic activity of the caregiver, level of income, degree of dependency, size of the municipality where the patient resides, regions, formal in-home care received, and formal out-home care received. The results of this model were estimated at a sample level of 1,298 individuals. This sample was extrapolated to the entire population with COPD, the results of which are shown in Tables 1 and 2.

Abbreviations: ME, marginal effect; SD, standard deviation.
