Table 4: Comparison between the levels of studied inflammatory biomarkers on admission and after 72 hours according to the outcome on the 14^th day^$.

Biomarkers	Stages	Outcome on the 14^th day			p value
		Non-survivors (8; 24.2%)	Survivors (25; 75.8%)
			On room air (14; 43%)	On O2 therapy or CPAP (11; 33%)
IL-6 (pg/ml)	Admission	376 .0 (26.3-511)	9.8 (0.1-39.4)	6.8 (0.3-14.2)	x^2= 4.846 P = 0.089
	72 hours	1.6 (0.1-187.6)	0.1 (0.1-0.3)	7.2 (0.1-41.3)	x^2= 7.003 p = 0.03*
IL-8 (pg/ml)	Admission	29.2 (9.1-164.5)	14.4 (10.4-26.1)	16.8 (9.6-28.9)	x^2= 0.447 p = 0.799
	72 hours	13.9 (4.8-23.6)	12.7 (7.9-24.8)	28.2 (13.0-55.6)	x^2= 3.125 p = 0.2
CRP (mg/L)	Admission	2.4 (2.5-3.3)	2.4 (2.0-3.4)	3.0 (1.9-3.5)	x^2= 0.844 p = 0.656
	72 hours	1.8 (0.7-2.3)	1.4 (0.2-2.2)	2.5 (2.0-2.8)	x^2= 4.687 p = 0.096

IL-6: interleukin-6, IL-8: interleukin-8, CRP: C-reactive protein, O₂: oxygen, CPAP: continuous positive airway pressure, x²: Kruskal Wallis test, ^$ all data are presented in median and interquartile range (IQR), *significant at p ≤ 0.05.
