Associations of early-life head circumference genetic risk score with head circumference at different time points in the Generation R Study and from UK Biobank data. On the x axis the different ages are shown at which the genetic risk score of the seven early-life head circumference SNPs is tested. On the y axis the beta’s and 95% confidence intervals from linear regression analyses are shown. Detailed data can be found in Additional file 1: Table S15
