FIGURE 1.

Median days to protease inhibitor initiation for each categorical factor in the final model (unadjusted). Patients with CD4 cell counts of 200 to 500 had large absolute delays in protease inhibitor initiation when compared with patients with CD4 cell counts less than 200. Although we are unable to report an exact median number of days to protease initiation for patients with CD4 cell counts greater than 500 (owing to a large number of censored subjects), the median is at least 560 days. Similarly, patients with a history of injection drug use (IDU) and depression had large delays in protease inhibitor initiation when compared with patients without those factors. Those patients with a history of pneumocystis carinii pneumonia (PCP) were started on protease inhibitors more rapidly.
