Table 2:

Test of Equality of Pre-HAART Trends

Outcome p-value

Domestic violence 0.258
Cocaine use 0.091
Heroin use 0.307

Joint significance 0.147

This table shows the p-values from tests that the pre-HAART trends in outcomes are parallel. For each outcome, we regress the outcome on age, age squared, race indicators, site of visit indicators, six-month time dummies, an indicator for being in the treatment group, and an interaction of the time bins and the treatment group. We then test that the pre-HAART interactions are zero.
