Contextual and individual inequalities of multimorbidity in Brazilian adults: a cross-sectional national-based study. BMJ Open 2017;7:e015885. doi: 10.1136/bmjopen-2017-015885. This article was previously published with some errors. ­ In table 1 and supplementary table 1, the percentages of the descriptive analyses, no full postestimation of complex sampling are performed resulting in minor discrepancies on decimal places. Absolute numbers are not affected. The issue didn’t affect the main results or the conclusions of the paper. The corrected numbers are displayed below.
