Complete-case-only analysis for Treatment comparison

a: Crude hazard ratios

b: Adjusted hazard ratios (multivariable Cox model; adjusted for number of antihypertensive drugs, peripheral vascular disease, cholesterol level, maximal glucose level, type of immunosuppression, year of transplantation, diabetes duration, donor age; 65 deaths, 65 graft losses).

c: Adjusted hazard ratio estimates from marginal structural Cox models; adjusted for number of antihypertensive drugs, peripheral vascular disease, cholesterol level, maximal glucose level, type of immunosuppression, year of transplantation, diabetes duration, donor age; 65 deaths, 65 graft losses).

Nonlinear estimation of adjusted association of glucose control and mortality Nonlinear estimation was performed using restricted cubic splines with knots placed at the 5th, 35th, 65th and 95th percentiles of the empirical distribution of each parameter (median glucose per year, HbA1c, maximal glucose per year).

Patient survival
a: Neither mean glucose levels (mg/dl) nor mean HbA1c (%) predicted mortality. Solid line indicate the HR, dashed lines the 95%CI.

b:

c:

d: The slope of this curve reaches a maximum at 207, i. e. at 207 there is maximal additional risk due to increase of maximal glucose by 1 unit
