In the fourth paragraph of the Discussion some rogue text was inadvertently inserted into the sentence ‘This is especially true of cohorts from table 1 LMICs where youLMICsildren youLMICsildren youLMICsildreniyouLMICsildrenidemicsand non-communicable diseases.’ The sentence should read: ‘This is especially true of cohorts from LMICs where young children are exposed to overlapping epidemics of infectious and non-communicable diseases.’ We have corrected this error and replaced with a revised version.
