PAEs, phthalate esters; DMP, dimethyl phthalate; DEP, diethyl phthalate; BBP, butylbenzyl phthalate; DEHP, di(2-ethylhexyl) phthalate; DNOP, di-n-octyl phthalate.
Demographic characteristics are expressed as mean ± standard deviation, gestational age, birth weight and length are also expressed (minimum, maximum) and PAE concentrations are expressed as median (25th–75th).
