This data is preliminary and we have not assessed exercise tolerance, or outcomes in those with presentations that did not require initial respiratory support. Assessments are ongoing in this cohort and in children presenting following infection with new variants of concern.ReferencePenner, et al. 6-month multidisciplinary follow-up and outcomes of patients with paediatric inflammatory multisystem syndrome (PIMS-TS) at a UK tertiary paediatric hospital: a retrospective cohort study.
