Evolution of median HIV-RNA load and CD4∶CD8 ratios in recently infected patients. Serna-BoleaCelia de DeusNilsa AcácioSozinho MuñozJose NhalungoDelino LetangEmilio AlonsoPedro NanicheDenise 2013 <p>HIV-RNA load (A) and CD4∶CD8 ratios (B) in patients with high HIV-RNA as compared to the other patients. Median and interquartile range are shown. HIV-RNA viral load groups are defined as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031859#s2" target="_blank">methods</a>. P-values are from Wilcoxon rank sum test between groups as follows: *p = 0.0001, **p = 0.038, *** p = 0.002. P-values from Wilcoxon Signed Rank between visits did not show significant differences. Numbers denote the n for each group at each time point.</p>
