The data were analyzed using log transformation of GDF15 levels ( Figure 2b ) and a highly significant relationship with the reciprocal of pre-pregnancy BMI was apparent (standardized β=0.266, p=4.1×10 -13 , n=721).This relationship was replicated in the NIPTeR Study ( Figure 2c & d ; standardized β=0.280, p=1.5×10 -5 , n=231).
