Table 2 Mean difference in hearing level (HL) at baseline and mean change in hearing level associated with variation in baseline plasma HIV RNA and baseline CD4+ T-cell count.*

From: A prospective study of hearing changes after beginning zidovudine or didanosine in HIV-1 treatment-naïve people

 

Baseline Plasma HIV RNA

(Population difference in dB per 10-fold increase)

Baseline CD4+ T-cell count

(Population difference in dB per 100 cells/mL increase)
