Fig 2. Adjusted odds ratios (95% CIs) of GDM risk in association with plasma phospholipid n-3 PUFA and n-6 PUFA at gestational weeks 10–14 and 15–26.

The point estimates were adjusted for age (years), gestational age at blood collection (weeks), parity (nulliparous, multiparous), family history of diabetes (yes, no), and prepregnancy body mass index (<25.0, 25.0–29.9, 30.0–34.9, 35.0–44.9 kg/m²). High, concentrations above median; low, concentrations below median. Obtained by the likelihood ratio test for the interaction between n-3 and n-6 PUFAs: *P for interaction = 0.08 at gestational weeks 10–14; ^†P for interaction = 0.02 at gestational weeks 15–26. GDM, gestational diabetes mellitus; PUFA, polyunsaturated fatty acid.
