Correction to BMC Public Health (2018) 18:1156 DOI: 10.1186/s12889-018-6065-6

It has been highlighted, that the original article [1] contained errors in Fig. 1. On the 3rd level, the first box should read “Records with any required information = 157” and the second box should read “Records without any required information = 0”. Those were incorrectly captured as “Records with complete information = 157” and “Records without any required information = 157” respectively in the original article. This Correction article shows the correct Fig. 1.
