Day 1	0.15	1.16	0.0281	0.87	1.54
Day 2	0.26	1.30		1.00	1.68
Day 3	0.26	1.30		1.06	1.58

Log₁₀(INR)	2.13	8.38	0.0004	2.41	29.14

Using NAC 1-2 as the reference group, all other groups show positive estimate values indicating higher likelihood of transplantation. Day 4 is the reference day that is then compared with the prior 3 days. The effect is greatest on Days 2 and 3 and less so for Day 1 compared to Day 4.
