Note: Standardized Prevalence Ratios were calculated to examine differences between drug user cohort, NJBRFS, and NHIS data. Boldface indicates statistical significance in two-tailed Fisher exact test (* p < 0.05 and ** p < 0.01).

PWID: Persons who inject drugs.

N.C.: Non-Calculable due to absence of data in the reference database, which excluded data when those databases had small numbers of persons in the cells; NH: Non-Hispanic.
