claim: lack of plasma angiotensin ii level is a potential pathogenesis for the critically ill covid-19 patients
evidence_1: h the plasma ang ii positive rate in the critically ill covid-19 cases was significantly higher than that of control.", "b the plasma ang ii concentration in the critically ill covid-19 cases and severe covid-19 cases was significantly higher than that of the mild covid-19 cases.", "therefore, elevation of ang ii triggered by interaction between ace2 and s protein of sars-cov-2 may be important pathogenic factors for critically ill covid-19 patients.", "plasma ang ii level in critically ill covid-19 patients was significantly higher than that of control and those with mild covid-19 symptoms (fig."
