Passmore SJ, Draper G

1998

England and Wales

The authors studied 597 cases and matched controls born 1968-85 and diagnosed 1969-86. the controls were matched for sex, month of birth and hospital of birth. The association between cancer and intramuscular vitamin K was of borderline significance (odds ratio 1.44, P=0.05); the association was strongest for leukaemia. The authors conclude that the possibility of an increased risk is not excluded.
