The bars and error bars below represent odds ratios (OR) and 95% confidence intervals for the risk of neurocognitive impairment associated with any grade 2 or higher condition. The black dotted line represents the null reference association (OR=1, no grade 2 or higher condition). Logistic regression models are adjusted for age at diagnosis, gender, race, time since diagnosis, any high-dose cytarabine and cumulative dose of high-dose methotrexate. Central nervous system (CNS) models are further adjusted for neurosurgery, cumulative cranial radiation dose, and intrathecal methotrexate dose.
