TABLE 4.

Adjusted length of stay of MIS‐C treatment regimens

	Group A (IVIG + Steroid)	Group B (IVIG)	Group C (Steroid)	Group D (None)
Hospital length of stay in days, geometric mean (95% CI)	5.4 (4.5, 6.6)	6.2 (4.7, 8.2)	6.7 (5.1, 8.6)	6.2 (5.2, 7.5)
Difference in hospital length of stay from control in days	−0.8 p = 0.19	0.0 p = 0.94	0.5 p = 0.61	NA
ICU length of stay in days, geometric mean (95% CI)	3.8 (3.0, 4.9)	4.5 (2.8, 7.0)	4.6 (3.2, 6.5)	5.4 (4.0, 7.3)
Difference in ICU length of stay from control in days	−1.6 p = 0.03	−0.9 p = 0.43	−0.8 p = 0.38	NA

Note: Hospital LOS, adjusted for age, number of abnormal inflammatory mediators, race (non‐Hispanic white versus not), comorbidity (including obesity), bacterial or viral coinfection, and ICU admission (≤2 days) or WHO ordinal scale ≥ 4 on admission. ICU LOS includes PRISM and the WHO scale/ICU admission variable is replaced by WHO ordinal scale ≥ 4 on admission only.
