CD4 and cytomegalovirus retinitis: Lower CD4 count (per 100 /μL decrement, OR 3.9, 95% CI 1.85–8.30, p<0.001) was also significantly associated with CMV retinitis, whereas presence of CMV diseases other than retinitis showed a trend toward association that was not statistically significant (OR 3.9, 95% CI 0.78–19.1, p = 0.097).
