Table 2.

Comparison between the two groups on the number of days of total Hospitalization, days of subintenive department, days spent in non invasive ventilation and days with high flow oxygen ventilation.

Days	Group Treated with Melatonin 2 mg PR (Mean ± Std. Dev.)	Group Treatd with Melatonin 2 mg PR (Median QR)	Control Group Untreated (Mean ± Dev. Std.)	Control Group Untreated (Median IQR)	p-Value
Hospitalization	31.3 ± 6.8		34.3 ± 6.9		0.03
In subintensive care	12.3 ± 3.2		20.1 ± 6.1		<0.001
With NIV Non Invasive Ventilation	5.2 ± 3.0	5 (3–7.3)	12.5 ± 4.2	11 (10–15.3)	<0.001
With High flow oxygen ventilation	7.1 ± 2.5	7 (5–8)	7.7± 3.2	7 (5–10)	0.436

NIV, non-invasive ventilation; IQR, interquartile range; PR, Prolonged-Release.
