Lower socioeconomic status, whether defined by general socioeconomic status, household income, education level, or insurance status, was generally associated with worse access to treatment, including stem cell transplantation[ 27 , 36 , 37 , 39 , 40 , 43 , 50 , 54 , 58 , 72 , 80 , 88 , 93 , 97 ], although this was not a universal finding [ 36 , 42 , 43 , 47 , 50 , 54 , 58 , 60 , 66 , 96 ].
