Worth note is the steady decrease in the proportion of HIV diagnosed
individuals, from 22.3% in 2000 to 10.7% in 2010. A similar trend was observed
in IV drugs (Intravenous drugs) dependents that decreased from 12.8% to
7.1% in the same period. Although more moderate, the proportion of new PTB
cases being alcohol dependent is also decreasing over time. Notice the
increase of the proportion of immigrants after the year 2005.
When looking at the risk factors by sex (Figure 3), it is very clear that the
percentage of men with a certain risk factor is always higher when compared
to women, except when an immigrant. This difference is quite remarkable
when looking at alcohol, where almost 25% of the men in the database are
alcohol dependent.

Although the total number of men and women are quite different (numbers
in brackets in Figure 3), these differences are indeed statistically significant
with a p < 0.001 for all the comparisons, with the exception of the proportion
of being an immigrant, which showed statistically significant differences
between sexes with a p = 0.040.
