Mean Knowledge and Attitude Scores by Number of People Who Inject Drugs Encountered per Workday. White columns represent mean knowledge scores ± SEM and gray columns represent mean attitude scores ± SEM. Providers indicated their number of encounters with people who inject drugs (PWID) per typical workday as binned into discrete categories (0, 1-2, 3-5, 6-8, and 9+) on the survey. Two knowledge means with the same lowercase letter are not significantly different at the 0.05 level. Note that providers who encountered 9+ PWID during a typical workday had significantly lower mean knowledge scores than all other categories except zero encounters. Two attitude means with the same uppercase letter are not significantly different at the 0.05 level. Note that providers who encountered 9+ PWID during a typical workday had significantly lower mean attitude scores compared to providers who encountered 3-5 or 6-8 PWID in a typical workday. The overall p value for knowledge differences is p < 0.001, and the overall p value for attitude differences is p < 0.0001
