In-hospital survival times of patients with and without hyperbaric oxygen therapy (HBOT)

HBOT	Mean			Median
	days	SD	95% CI	Days	SD	95% CI
Total cohort	90.5	6.6	77.5–103.5	106.0	23.6	59.8–152.2
HBOT subgroups
No, not indicated	82.5	6.2	70.4–94.6	106.0	28.8	49.5–162.5
Yesa	91.8	10.5	71.2–112.4	81.0	n.d	n.d
No, ineligible	50.3	16.6	17.6–82.9	16.0	8.3	0.0–32.2

Mean and median in-hospital survival times were defined as days from admission to our or another hospital until death or discharge from our hospital

CI confidence interval, n.d. not determined, SD standard deviation

^aIn the subgroup with HBOT, the SD and 95% CI of the median in-hospital survival time could not be calculated due to lack of variability after the median
