Comparison of serum MMP3 between infected group and
non-infected group
Normality tests indicated that data from both the novel coronavirus
pneumonia infected group and the non-infected group were not normal.
Therefore, the Wilcoxon rank sum test was used to compare the 2 groups.
The MMP3 serum levels in the infected and non-infected groups are shown
(Table 1). MMP3 concentrations were
44.44(23.46~72.12)ng/ml in the infected group and
32.42(28.16~41.21)ng/ml in the non-infected group. A
positive correlation was found between infected and non-infected groups
(Z=-2.799,
P=0.005<0.05). The distribution of MMP-3 and the statistical
significance between the 2 groups were plotted using a quartile box
(Fig. 1).
