Demographics of included and excluded presentations Data are shown as mean and SD for continuous variables and as count and percentage for categorical variables.

IMOP, impaired mobility on presentation; NEWS, National early warning score; SMD, standardized mean difference; SD, standard deviation. as the excluded group included repeat presentations, mortality could not be calculated.
