Medically diagnosed infections and risk of childhood leukaemia: a population-based case–control study

摘要

Background Previous studies on the association between childhood infections and childhood leukaemia have produced inconsistent results, likely due to the recall error/bias of infection data reported by the parents. The current study used a population-based and record-based case–control design to evaluate the association between childhood leukaemia and infections using the National Health Insurance Research Database of Taiwan.
