Kaplan Meier methods were used to determine survival statistics on patient progression and survival based on age (>3 years), sex, tumor location, grade, level of resection, radiation, chemotherapy and telomerase status, as well as mouse survival following orthotopic injection.
An unhappy student named Ernie, who had been held back several times, made a deep impression on him, spurring his thinking about how grade levels based on age were, as he wrote later in "A Place Called School," little more than "an adult convenience for classifying, tracking, assessing, advancing, and retarding the millions of students who move through it".

This scoring system is based on age, previous episode of diarrhoea and GBS disability-grade at 2 weeks of treatment.
Isocitrate dehydrogenase (IDH) mutation status and grade define subgroups of diffuse gliomas differing based on age, tumor location, presentation, and prognosis.
