Longitudinal profiles of plasma even-chain and odd-chain SFAs throughout pregnancy according to gestational age intervals among women with and without GDM. Even-chain SFAs: sum of myristic acid (14:0), palmitic acid (16:0), and stearic acid (18:0); odd-chain SFAs: sum of pentadecanoic acid (15:0) and heptadecanoic acid (17:0). Values are mean percentages ± SEs. *P < 0.05, **P < 0.01, ***P < 0.001 for case-control comparisons obtained by linear mixed models with associated likelihood ratio tests accounting for matched case-control pairs at each gestational age interval. P-interaction between gestational weeks and GDM status was 0.042 for even-chain SFAs and <0.001 for odd-chain SFAs, obtained by likelihood ratio test. GDM, gestational diabetes mellitus.
