Intensity of informal care	CI	0.0094***	0.0084***	0.0206***
	Confidence interval	0.008 to 0.011	0.008 to 0.009	0.012 to 0.030

Note: EI and CI represent inequity indices for actual use, HI represents horizontal inequity, and ADL represents activities of daily living. EI = Erreygers concentration index; CI = concentration index; HI = horizontal inequity index.
