Maternal Body Mass Index and Risk of Congenital Heart Defects in Infants: A Dose-Response Meta-Analysis

Figure 4

The dose-response analysis between maternal BMI and CHDs risk in infants with restricted cubic splines in a multivariate random-effects dose-response model. The solid line and the long dash line represent the estimated RR and its 95% CI. Short dash line represents the linear relationship (per 5 kg/m² increment). RR, relative risk; CI, confidence interval; BMI, body mass index.
