Multivariate regression analysis for primary outcome of 60-day mortality and secondary outcomes in those with a platelet decrease following RRT initiation.

Outcome	Odds Ratio with 95% Confidence Interval
	Platelet Decrease^a (Model 1^b)	Platelet Decrease^a (Model 2^c)
60-day Mortality	1.51 (1.12 - 2.02)	1.48 (1.07 – 2.06)
28-day Mortality	1.30 (0.97 – 1.75)	1.26 (0.91 – 1.75)
1-Year Mortality	1.23 (0.92 – 1.63)	1.20 (0.88 – 1.63)
Renal Recovery	0.94 (0.68 – 1.29)	0.96 (0.70 – 1.32)
RRT Free Days	1.10 (0.92 – 1.31)	1.12 (0.95 – 1.32)
ICU Free Days	0.96 (0.89 – 1.03)	0.93 (0.88 - 1.00)
Hospital Free Days	0.88 (0.78 – 0.99)	0.89 (0.79 – 0.99)
