Serum MEHP concentrations in the cord and corresponding PND28 infant in NICU (n = 49) and dialyzed patients (n = 110). PVC-free tubes were used for feeding the infants in NICU [87, 88]. The serum from the dialyzed patients was collected before a hemodialysis session using plasticizer-free tubes with written informed consent. Data for the serum MEHP concentrations after the hemodialysis session have been presented in our previous paper [89]. The analytical methods have been described elsewhere [7]. *p < 0.05 compared with the other groups
