Abbreviations: SD standard deviation
There were no missing data for any of the variables, except deprivation score as described below
aAll models adjusted for age, except the model with age as the independent variable of interest which is a univariate model
b221 patients only (missing for all care home patients and 2 existing inpatients). Deprivation score was measured using Pobal HP Deprivation Index (PDI), which is an Eircode-based relative measure of deprivation. Deprivation scores are not generated for care home residents
cPercentage out of total number of patients with that characteristic
