Fig 2. Incidence of positive urine dipstick albumin in patients on long-term low-dose aspirin therapy in the intention-to-treat analysis.

Positive urine dipstick albumin developed in 297 patients in the aspirin group and 270 patients in the no aspirin group. The intention-to-treat analysis showed that low-dose aspirin did not increase the incidence of positive urine dipstick albumin (HR, 1.17; 95% CI, 0.995 to 1.38; log-rank P = 0.057)
