Figure 2From: HIV-1 tropism: a comparison between RNA and proviral DNA in routine clinical samples from Chilean patientsRelationship between HIV viral tropism and the median of the logarithm of viral load. The figure shows the median of the viral load of carriers of R5 (n = 61) and X4 (n = 30) strains. The difference in the mean values of the two groups is greater than would be expected by random; there is a statistically significant difference between the input groups (P = 0.017). * = p < 0.05.Back to article page
