CD4 and glioblastoma: In multivariable analysis adjusted for other factors, the odds of being reclassified for GBM were three times those of heterosexual men and women (adjusted odds ratio [aOR] 3.54; 95% confidence interval [CI] 3.14–3.98; p < 0.001) and the odds for those with a baseline CD4 between 200 and 350 cells/mm3 were three times those with a CD4 <200 cells/mm3 (aOR 3.21; 95% CI 2.88–3.58; p < 0.001).
