Figure 1.

The Kaplan-Meier estimates of the proportions of patients with insulin independence and A1C ≤6.5% (A and B) and with persisting graft function (basal C-peptide ≥0.5 ng/ml) (C and D). Left panels represent these proportions among the entire cohort (number at risk: 14 at baseline and at 2 years, 7 at 3 years, and 3 at 4 years) and right panels in patients with optimal initial graft function (solid line) (n = 9) and in those with suboptimal initial graft function (interrupted line) (n = 5). Circles indicate censored data. *Mantel-Cox log-rank test, optimal PGF vs. suboptimal PGF.
