Maternal consumption of coffee and tea during pregnancy and risk of childhood ALL: a pooled analysis from the childhood Leukemia International Consortium

We investigated the effects of maternal coffee and tea consumption during pregnancy on ALL risk by pooling data from eight case-control studies participating in the Childhood Leukemia International Consortium.
