Outcomes of patients included in the observational study.

Outcome	Vitamin C group (n = 10)	Control group (n = 103)	p-value
Vasopressor-free days, days	9.0 (0.0–24.0)	0.0 (0.0–14.0)	0.271
Continuous renal replacement therapy-free days, days	26.0 (6.8–28.0)	19.0 (5.8–28.0)	0.644
Ventilator-free days, days	0.0 (0.0–18.5)	0.0 (0.0–15.0)	0.832
ICU-free days, days	0.0 (0.0–3.3)	0.0 (0.0–8.0)	0.667
ICU-mortality	2 (20.0)	49 (47.6)	0.110

n, number; ICU, intensive care unit.

Data are presented as median (interquartile range) or number (%).

Vasopressor-free days, continuous renal replacement therapy-free days, ventilator-free days and ICU-free days were calculated by the number of days in the first 28 days following intubation that a patient was alive and not receiving vasopressors, not receiving continuous renal replacement therapy, not on a ventilator or not in the ICU, respectively. All outcomes were censored at day 28 following intubation.
