Longitudinal Cluster Analysis of Hemodialysis Patients with COVID-19 in the Pre-Vaccination Era.

Nasopharyngeal swabs for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) were performed on HD patients presenting recent contact with COVID-19-positive patients and/or with fever or respiratory or gastrointestinal symptoms suspected of COVID-19. Table 2 Validation cohort of cluster analysis performed using COVID-19-positive HD patients: General characteristic and comparison between patients assigned to different clusters. The rationale for testing this strategy in this population is that HD patients constitute a peculiar subgroup of COVID-19 patients. This observation is also valid for maintenance hemodialysis (HD) patients, representing a distinct subgroup of COVID-19 patients [[2]]. [Extracted from the article]
