Values are means (sd) or percent, as appropriate. All P-values < 0·0001, except residential area (P-value = 0·84). P-values refer to P-trend estimated using linear contrast tests for continuous variables, Mantel–Haenszel chi-square trend tests and chi-square tests for ordinal and categorical variables, respectively.
