ORs were calculated by comparing the low activity allele H vs. the intermediate activity allele Y in lung and UADT cancers. P-values of the ORs are calculated with the DerSimonian-Laird method using a random effects model and measurements of heterogeneity are based on Cochran's Q-test and the inconsistency index I 2.
