Bioelectrical values of COVID-19 disease: non-survivors (n = 16) and survivors patients (n = 111). R: resistance (Ohm); Xc: reactance (Ohm); H: height (m); (R/H) and (Xc/H): R/H and Xc/H standardized for sex and age using bioelectrical Italian standards. Red point: non-survivor patients; Black point: survivor patients. The bioelectrical impedance vector distribution analysis shows a situation of inflammation and cellular injury associated with COVID-19. The lower right quadrant encompasses patients with decreased cell mass and hyperhydration, most of the deceased patients.
