Abbreviations: AT, adipose tissue; IA, internal abdominal; IHCL, intrahepatocellular lipid; SCA, subcutaneous abdominal.
P represents significance of infant sex in overall analyses. Data are mean and (95% confidence intervals) and P-values from multivariable regression, except where * denotes percentage difference (95% confidence intervals) following log transformation and ** denotes P-values from multivariable regression of natural log-transformed data (performed using transformed data due to non-normal distribution of residuals).
