Fig 1. Comparison of serum concentration of MMP3 between the
COVID-19 infected group and non-infected group. Box above with the
median as a line shows the distance between the quartiles, and the
maximum and minimum values of MMP3 were presented by the whiskers.
Outliers are displayed as separate points. The P-values show that there
was significant difference between groups.
Fig 2. Changes of serum MMP3 concentration in novel coronavirus
patients during hospitalization. The interval of each test was 6 days,
and a total of 5 times were tested. Box above with the median as a line
shows the distance between the quartiles, and the maximum and minimum
values of MMP3 were presented by the whiskers. Outliers are displayed as
separate points.
