↵a ANOVA P-values are from a likelihood ratio test, the remainder are Wald P-values.
↵b CQC rating was converted to a numeric scale for all analyses (1 = outstanding, 2 = good, 3 = requires improvement) in order to model this variable. ANOVA = analysis of variance. CQC = Care Quality Commission. EMIS = Egton Medical Information Systems. IMD = index of multiple deprivation. OR = odds ratio. QMC = Queen’s Medical Centre. QOF = Quality and Outcomes Framework.
