Table 1

Results for the predictors of logit of incidence of catastrophic health expenditure as a function of the percentage of OOP_EXP, the percentage of HEX_GDP and the GDP_C

Coefficient	Estimate	SE	p Value
logit(OOP_EXP)	0.67	0.16	<0.001
logit(HEX_GDP)	0.67	0.34	0.048
ln(GDP_C)	−0.38	0.14	0.005

Goodness of fit, R²=0.69. Number of observations, 110. The variance of country random effects was 0.29.
GDP_C, gross domestic product per capita; HEX_GDP, health expenditure within the share of gross domestic product; OOP_EXP, out-of-pocket expenditure within total health expenditure.
