CRP and COVID-19: Table 4 illustrates the relationships between all parameters and EMAP-II in the severe COVID-19 patient group. EMAP-II Ct revealed significant positive associations with lymphocyte percentage and O2 saturation in the severe COVID-19 patient group (p < 0.001). EMAP-II Ct showed a negative relationship with ferritin, CRP, and D-dimer levels (p < 0.001). Moreover, EMAP-II Ct showed a negative association with age (p = 0.023).
