Table 1 Comparison of characteristics of patients infected with a subtype B virus and patients infected with a virus of the non-B subtypes.

From: Epidemiological study of phylogenetic transmission clusters in a local HIV-1 epidemic reveals distinct differences between subtype B and non-B infections

  1. Values are given as counts per number of patients for which data was available. For the multivariate analysis, odds ratios are given with regard to Subtype B infection. The p-value for the Hosmer-Lemeshow test for the multivariate model is 0.528.
  2. HBV, Hepatitis B virus; HCV, Hepatitis C virus; DRM, Drug resistant mutations; PHI, Primary HIV infection; IQR, interquartile range; CI, confidence interval.
