CRRT circuit survival.

CRRT circuit survival	CVVH/RCA2.2	CVVHDF/RCA3.0	P value
Primary outcome
CRRT circuit survival—excluding circuits terminated because of (i) diagnostic procedures or interventions (operations) outside the ICU, (ii) technical errors, and (iii) circuits ended because of the decision to cease CRRT (hours) (median (IQR))	22.9 (11.4–48.6) (n = 179)	39.6 (19.5–67.3) (n = 168)	<.001
Circuit survival in COVID-19 negative patients (hours) (median (IQR))	22.2 (11.2–44.9) (n = 140)	40.8 (23.1–68.4) (n = 96)	<.001
Circuit survival in COVID-19 positive patients (hours) (median (IQR))	24.9 (12.0–62.4) (n = 39)	36.6 (17.3–66.9) (n = 72)	.30
CRRT circuit survival including all circuits
(hours) (median (IQR))	23.1 (11.8–46.2) (n = 257)	32.1 (15.2–65.7) (n = 290)	.001

n = number of circuits.
