Association between the level of suPAR in serum from 314 HIV-1–infected patients and overall survival.

Patients were divided into 3 strata based on the serum suPAR values, yielding similar numbers (n = 104-105) of patients in each stratum. The 3 curves in the figure thus represent patients with serum suPAR levels lower than 3.28 ng/mL (low), 3.28 to 4.19 ng/mL (medium), and higher than 4.19 ng/mL (high). The overall difference between the groups was highly significant (P < .0001; χ² = 63; log-rank test). The number of patients at risk after each 12-month interval is indicated below the figure.
