Gestational diabetes is associated with change in the gut microbiota composition in third trimester of pregnancy and postpartum.

When regressing alpha diversity measures against glycaemic traits, we found a nominally significant association ( P = 0.02) between the number of observed OTUs and beta cell function represented by the disposition index, but the association was insignificant at a 10% false discovery rate (FDR) ( Q = 0.2) (Additional file 1 : Figure S5).
