Odds that an HIV-1 sequence was defective in anatomic sites versus plasma samples. Shown is a comparison of the odds that an HIV-1 RNA sequence from pre- and on-ART plasma samples was defective versus the odds that a viral DNA sequence from PB, LN, and gut tissues was defective for the AHI group (open squares) and the CHI group (solid squares). The comparison of the odds is indicated as the OR; the error bars indicate the 95% confidence intervals for the ORs. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001. p6-RT sequences were used for the genetic comparisons. The odds ratios and their confidence intervals were estimated by logistic regression models.
