FIG 1.

Proportion of Children’s Oncology Group (COG) study enrollments categorized as cancer control or AYA, by institution type (2004 through 2013). Whereas proportional enrollment onto COG cancer control studies was significantly greater at CCOP than non-CCOP sites, the proportional enrollment of AYA patients was significantly lower (see Methods for calculation of cancer control and AYA proportional enrollments). The P value represents the difference in proportional cancer control or AYA enrollment between sites. AYA, adolescent and young adult; CCOP, Community Clinical Oncology Program.
