Figure. Kaplan-Meier Estimates of 30-Day to 1-Year All-Cause Mortality Among Groups A, B, and C.
The overall log-rank P value for groups A (improvement in renal function), B (no change in renal function), and C (worsening of renal function) was .01. The log-rank P value for group A vs B was .22 (hazard ratio, 0.79; 95% CI, 0.54-1.16). The log-rank P value for group A vs C was .003 (hazard ratio, 0.55; 95% CI, 0.37-0.82). The log-rank P value for group B vs C was .07 (hazard ratio, 0.70; 95% CI, 0.47-1.03). Pairwise comparisons are also shown.
