INS and acute kidney injury: An association between covid-19 and an increased odds of acute kidney injury, renal replacement treatment, use of insulin, pulmonary embolism, stroke, myocarditis, arrythmia, and increased troponin was found in US veterans admitted to hospital with covid-19 versus a control group of patients with seasonal influenza.28 The index event was admission rather than discharge, so the results are not strictly comparable with our study, but suggest physiological changes in multiple organs after admission to hospital for covid-19, supporting our findings.
