Figure 2. Kaplan–Meier Analysis of the Primary End Point.
Shown are the percentages of patients who were free from the primary end point — the diagnosis of tuberculosis or death from tuberculosis or an unknown cause — among all the patients (Panel A), among those with a CD4+ count of 250 cells per cubic millimeter or less (Panel B), and among those with a CD4+ count of more than 250 cells (Panel C), according to the receipt of either a 1-month regimen of daily rifapentine plus isoniazid (1-month group) or 9 months of isoniazid alone (9-month group).
