Eurostat's official Healthy Life Years (HLY) estimates are based on European Union Statistics on Income and Living Conditions
(EU-SILC) cross-sectional data. As EU-SILC has a rotational sample design, the largest part of the samples are longitudinal,
health-related attrition constituting a potential source of bias of these estimates. Bland-Altman plots assessing the agreement
between pairs of HLY based on total and new rotational, representative samples demonstrated no significant, systematic attrition-related
bias. However, the wide limits of agreement indicate considerable uncertainty, larger than accounted for in the confidence
intervals of HLY estimates.
