Baseline hospital performance and the impact of medical emergency teams: Modelling vs. conventional subgroup analysis

Table 6 Subgroup analysis results using medians of the baseline incidences as the cut-off values

	Change in incidence of primary outcome	Change in incidence of unexpected cardiac arrests	Change in incidence of unplanned ICU admissions	Change in incidence of unexpected deaths
Group with baseline incidence ≥ medians
Weighted difference (MET versus Control)	0.402	0.536	0.091	0.222
