Fig. 4From: Immunological risk stratification and tailored minimisation of immunosuppression in renal transplant recipientsBiopsy-proven acute rejection (BPAR) rates. Kaplan-Meier estimates for BPAR by immune risk group (a), donor type in low-risk (b), and in high-risk (c) recipients. Numbers at risk at various time points is given below each graph. Graph beyond 400 days should be interpreted with caution due to low ‘numbers at risk’Back to article page
