1. prophylaxis against haemorrhagic early 1970s the percentage of babies given vitamin K increased by about 30%, with a similar increase taking place in the next decade. The increase in the disease of the newbom in the United Kingdom;Handel, J.; Vitamin, Tripp J.H.; K.;BMJ,1991
2. Pre-natal irradiation and childhood malignancy: a review of British data from the Oxford survey. incidence of leukaemia in the 1960s is compatible with most of the increase in use of vitamin K being due to intramuscular administration with a relative risk of 2 0, which is similar to the argument BrJ7Cancer;Bithell, J.F.; Stewart, A.M.,1975
3. Trends in childhood leukaemia in Britain 1968-1978;Stiller, C.A.; Draper, G.J.;BrJfCancer,1982
4. The national registry of childhood tumours and the leukaemia-lymphoma presented by Golding and colleagues. If, on the other hand, we accept their relative risk estimate of 2-65 for leukaemia, we have to data for 1966-83.

5. Incidence assume that about half the increase in use of vitamin K is accounted for by oral administration. This seems unlikely, which suggests that the risk, if it exists, is less. For the remainder of the period rates nationally and in administratively defined areas.
