In contrast, the impact of renal comorbidity on the mortality from COVID-19 has been well described [60,61,62,63], and the prognostic importance of CRP [21,22,24,64,65,66] and BUN [22,23,25,67,68,69,70,71] has been clearly reported as evident in multiple ML studies and meta-analyses. This evidence concerns the gene CRP and COVID-19.
