Table 2. Multivariate associations (hazard ratios and 95% confidence intervals derived from joint models) for access to transplantation for BMI in different multivariate joint models stratified on three levels of initial BMI with competing risk of death.

	Hazard Ratio [95% Confidence Interval] Probability of renal transplantation for each 1 kg/m2 decrease in the BMI per year
	10.5–23 (n = 6 456)	23–30 (n = 8 605)	≥30 (n = 4 463)
Model 1: adjusted for age and gender	1.01 [0.99–1.02]	1.05 [1.03–1.06]	1.11 [1.09–1.12]
Model 2: adjusted for age, gender and comorbidities	1.00 [0.98–1.01]	1.03 [1.02–1.05]	1.10 [1.08–1.11]
Model 3: adjusted on age, gender and eGFR (CKD–EPI)	1.02 [1.00–1.04]	1.05 [1.04–1.08]	1.11 [1.10–1.14]
Model 4: adjusted on age, gender and initial treatment	1.00 [0.98–1.02]	1.05 [1.03–1.06]	1.11 [1.09–1.12]
Model 5: adjusted on age, gender and smoking status	0.99 [0.97–1.01]	1.04 [1.03–1.06]	1.10 [1.09–1.12]
Model 6: adjusted for age, gender, comorbidities and albuminemia level	1.01 [0.99–1.04]	1.02 [1.00–1.04]	1.09 [1.06–1.10]

Abbreviations: eGFR, estimated glomerular filtration rate; CKD–EPI, Chronic Kidney Disease Epidemiology Collaboration.

NB: A crude model not possible to compute due to a limitation in the current implementation of the code to do the competing risks.
