GSTM1 and intrahepatic cholangiocarcinoma: Bora and colleagues performed a basic intent-to-treat analysis, comparing 6-month serum ferritin and Hb levels of infants randomised to long umbilical cord and milking (the umbilical cord was clamped at 40 cm length and milked) and to ICC (the cord was clamped within 30 seconds of life at 5 cm from the umbilicus, but no milking was performed).
