RRR, relative risk ratio.
Model 1 – Outcomes within 0−2 days, unadjusted.
Model 2 – Outcomes between 3−14 days, unadjusted.
Model 3 – Outcomes between 3−14 days, adjusted for age and sex.
Model 4 – Outcomes between 3−14 days, adjusted for age, sex and pre-existing comorbidities.
Model 5 – Outcomes between 3−14 days, adjusted for age, sex, pre-existing comorbidities, and baseline NEWS2 score.
