Table 3 Cox Regression Analysis of Factors Associated with Hospitalized Poisonings

N	HR^A (95% CI)	P value
BMI <21.6 vs. >28.3 kg/m²	3.02 (1.45–6.28) ^B	0.003
Rejection within 6 months after transplant	1.83 (1.15–2.89) ^B	0.011
N in Final Model	21,575

^AAdjusted hazard ratio by Cox Regression analysis of time to hospitalization for poisonings, 95%CI = 95% confidence interval Analysis using these variables was limited to patients who survived at least 6 months after transplant ^CAnalyzed as a time-dependent covarariate, all times after graft loss = 1, all times before graft loss = 0
