Two separate logistic regression models were used. ^aVariables controlled for in regression A were gender, deprivation and age (adjusted odds ratio for year of age is included in Figure 1). ^bVariables controlled for in regression B were month, weekday, hour^†, bank holidays and Christmas period (AOR for hour is included in Figure 2).
