Table 4

Adjusted least square means (LSM) and regression coefficients (β) for weight at 20 months stratified by tertiles of PFOS, PFOA, and PFHxS and tertiles of birth weighta in a sample of British girls in 1991–1992.

Upper tertile > 3,580 g (n = 106)Middle tertile 3,200–3,580 g (n = 107)Lower tertile < 3,200 g (n = 107)
