Eligible studies examining the impact of socioeconomic status upon outcome in children with cancer in high-income countries.

ALL – acute lymphoblastic leukemia; AML – acute myeloid leukemia; CNS – central nervous system tumors; EFS – event free survival; ES – Ewing sarcoma; GCT – germ cell tumors; HR – hazard ratio; LR – log rank; MB – medulloblastoma; N – number; NB – neuroblastoma; NHL – non-Hodgkin lymphoma; OR – odds ratio; OS – overall survival; OST – osteosarcoma; RR – relative risk; SES – socioeconomic status; STS – soft tissue sarcoma; UK – United Kingdom; USA – United States of America. Bolded variables indicate statistically significant associations. Magnitudes of non-significant associations and confidence intervals of significant associations can be found in Table S2, along with definitions of each variable. aEducation measures also include occupation-based measures. bIndividual malignancies within the overall category showed no significant association between SES and outcome. cAdolescent and young adult population. dImmigrant patients from one center were compared to a historical control. eWithin the overall malignancy category, leukemias did show a significant association between lower SES and inferior outcome. fNo statistical analysis was presented, though the authors state that survival was “directly related to SES”.
