2. METHODS
2.1 Design and Setting
This study used a cross-sectional design. We enrolled 7-18-year-old
children with solid tumors after they were consented to participate in
this study from the AFLAC Cancer and Blood Disorder Center in Children’s
Healthcare of Atlanta (CHOA) in Atlanta, Georgia. Age, sex, and
race-matched healthy controls were recruited via flyers, online e-news
blast, and ResearchMatch (a disease-neutral web-based recruitment
registry).
