Mean ± SD (all such values). Adjusted means were calculated by using general linear regression models with adjustment for age (in 5-y intervals) and study area, where appropriate. SEs for each mean value in this table can be calculated as SD/√n, where n is the number of participants in that group. All P-heterogeneity and P-trend across subgroups <0.0001.
