Plasma Level of sACE2 (ng/mL).

Study Group	DOA	Day 7
Healthy Control (n-4)	0.828 (0.394–1.328)
Moderate (n-20)	9.072 (7.245–10.8)	9.873 (8.44–11.1)∗
Severe (n-22)	11.21 (8.955–14.53)	14.38 (12.6–20.27)∗∗∗
All COVID-19 (n-42)	9.597(8.63–12.08)	11.85(9.976–14.43)∗∗∗

Since the data was found to be non-parametric, the Related Sample t-Test (Wilcoxon Signed Rank Test) was used to compare the data within the groups. The results were expressed as median (IQR).

∗Indicates the P ≤ 0.05 when compared to DOA within the groups.

∗∗∗ Indicates the P ≤ 0.001 when compared to DOA within the groups.
