However, it should be noted that the estimates of the relationship between HI (income coded 0,1,2) and the tumor p53 mutational status were relatively stable using logistic regression models starting with the unadjusted analysis (OR  =  0.55, 95% CI: 0.3 to 1.02) and then applying the models shown in 2. This evidence concerns the gene TP53 and neoplasm.
