Coagulation parameters and inflammatory markers. Comparison between UC-MSC (red line) and placebo (blue line) groups over time. The bars show standard deviations (SD). *p ≤ 0.05 for comparison between groups (black asterisk). Statistical differences inside groups, longitudinal follow-up, were depicted in the graphs (UC-MSC—red line, placebo—blue line). *p ≤ 0.05 and **p ≤ 0.01 for longitudinal follow-up (red and blue asterisks). A D-dimer, B Platelets, C Neutrophils, D Ferritin and E C-Reactive Protein. UC-MSCs, umbilical cord mesenchymal stromal cells
