RESULTS
Of the 2,008 evaluable children, 279 (14%) were obese and 117 (6%)
were underweight at diagnosis. Demographic, disease, and treatment characteristics by weight category are listed in Table 1. No significant
differences in the presence of CNS disease, elevated WBC count by
continuous or categorical variable, or classification as SER versus RER
were found among the three weight groups, although T-cell phenotype
was somewhat less common among underweight patients. Patients
who identified themselves as Hispanic were more prevalent in
the obese category, whereas Caucasians were slightly underrepresented
in that category. These differences were not found to be of
independent statistical significance consistently across the multivariable
models.
