  1. Relative haplotype frequencies adjusted for sex, duration of injection drug use and HIV-1 serostatus.
  2. Haplotypes appear in order of descending haplotype frequencies among the comparison group stratified by race.
  3. P-value for LYPC among European Americans is not statistically signficant due to permutations based on small haplotype frequencies.
  4. The global score test evaluates differences between cases and controls in the overall haplotype distribution.
