Question special

I looked through exclusion criteria listed in both the article and supplemental publication in addition to Table 1, but was unable to find a section specifying if and which comorbidities the patients suffered. I understand SOFA scores reflect degree of organ dysfunction but these may also be impacted by chronic illnesses. For example, in our ICU populations, many patients will have concomitant DM2, for example, which already places the pt at higher mortality risk.
