Table 2 shows serum biomarkers of maternal metabolic health. A positive correlation between maternal ppBMI and the leptin/total adiponectin ratio was found only in the −LNS group. There were multiple correlations with other amino acids that can be found in Table S2. Analysis of correlations between BCAA and serologic markers of insulin resistance and all other amino acids are shown in Table S3. This evidence concerns the gene ADIPOQ and Insulin resistance.
