⁽¹⁾Sibling characteristics as reported in the SSH, except for the first registration in the HDSS.

⁽²⁾In manual linkages, the sibship size was not significantly associated with the outcome variable in the bivariate regression but we included it among the predictors of the adjusted model to be consistent with probabilistic linkages.
