Trend of creatinine levels change in patients diagnosed with COVID‐19, who were admitted to the hospital with acute kidney injury later and treated with an invasive ventilator (n = 17). The solid line represents the dead patients (n = 11) who died, and the dotted line surviving patients (n = 6). The blue vertical line represents the median time of AKI occurrence (16 days), and the orange vertical line the median time of cytokine storm occurrence (13 days). The purple vertical line represents the median time of initiating invasive ventilator treatments (6 days). The cytokine storm occurred 3 days before AKI, and patients died or were discharged on average 6 days after AKI. AKI, acute kidney injury
