Lancet Glob Health 2020; —In this Article, some data were misclassified by subgroup in the meta-analysis and an article from the Seychelles (Laird et al, 2017) was omitted from the meta-analysis. The estimates for the prevalence of vitamin D deficiency and mean vitamin D concentration have been adjusted as a result of these corrections, but the changes had no effect on the conclusions of the study. Further detail of the corrections is provided in the accompanying Correspondence.1, 2 The corrections have been made as of March 15, 2022.
