Fig 4.

Model used to identify potential patients with covid-19 for early discharge after 48 hours of observation. A decision threshold was chosen that achieves a negative predictive value of ≥95%. Figure depicts both the proportion of patients who could be discharged early and the number of bed days saved, normalized by the number of correctly discharged patients in each validation cohort. Results are computed over 1000 bootstrap replications. MM=Michigan Medicine; A-G represent the external validation cohorts
