However, in the second model, which excluded antenatal levels of blood manganese but included levels of cord blood manganese during birth, the coefficient was of similar magnitude but was only marginally significant for both cognitive (B = -2.20, p = 0.06) and language skills (B = -2.17, p = 0.08). 3.2.2 Non-significant findings The three studies that did not find a significant association between antenatal depression and cognitive outcomes received good [ 53 ] and fair [ 48 , 54 ] quality ratings.
