Joint associations between childhood acute lymphoblastic leukemia (ALL) and the variables combining the non-genetic factors of interest with rs10740055 (ARID5B) and rs4132601 (IKZF1) polymorphisms. The analyses addressing common infections were restricted to the children aged one year or more (398 controls and 426 ALL), while the analyses addressing the other exposures were based on the whole sample (442 controls and 434 ALL). Here, ARID5B is linked to acute lymphoblastic leukemia.
