RR of under-5 mortality by parent's education (maternal and paternal) and child age

(A) These RR curves show fitted average effect sizes in normal space across the full range (0–18 years of parental education) of exposures. (B) This figure shows how the underlying, normalised data were synthesised to produce the RR curves; normalised ln(RR) can be interpreted as the instantaneous slope of the RR curve implied by each study; data are superimposed with a synthesised average effect size; all of this is done separately by age group, and the other age groups estimated in the model are presented in appendix 1 (p 9). DHS=Demographic and Health Survey. RR=relative risk.
