Relative Risks of PICU Mortality Among Groups of Interest

Groups	Total Prevalence, n = 401, %	PICU Mortality, n = 44, n (%)	Relative Risk (95% CI)
Single organ failure	27.9	1/112 (0.9)	0.09 (0.01–0.65)
MOF	72.1	43/289 (14.9)	Not applicable
MOF no phenotype	46.9	19/188 (10.1)	Reference
MOF with phenotype	25.2	24/101 (23.8)	2.35 (1.36–4.08)
Immunoparalysis associated MOF	21.2	17/85 (20.0)	1.98 (1.08–3.61)
Thrombocytopenia associated MOF	9.2	16/37 (43.2)	4.28 (2.43–7.52)
Sequential liver failure associated MOF	1.7	3/7 (42.9)	4.24 (1.63–11.03)

MOF = multiple organ failure.

Results are based on individual univariable modified Poisson regression models.
