(a) Proportions of tumors classified as grade II (dark gray) or grade III (light gray) among trial cohorts. (b) Proportions of tumors classified as grade II (dark gray) or grade III (light gray) in two trial cohorts (SFOP & CNS9904) before (phase 1; pre-TR) or after (phase 3; post-TR) review of CNS9204 cohort in phase 2 of study (TR).
