“…The odds ratio for children whose bedrooms had MF levels of 0.4 microT or higher compared with the reference category (MF levels below 0.1 microT) was 2.6 (95% CI=0.76-8.6) for AML (Acute myelocytic leukemia) + ALL (Acute lymphoblastic leukemia) and 4.7 (1.15-19.0) for ALL only. Ed: 2.6 means 160% more likely. 4.7 means 370% more likely.
