Corrigendum to: The role of illness acuity on the association between frailty and mortality in emergency department patients referred to internal medicine

In the original version of this manuscript, an error occurred in the abstract. For the line, `a minority (307; 38%) were classified as having low acuity (CTAS: 1–2)', `low' should read `high'. This has now been corrected and the author apologises for the error.
