*Results for all hospital analysis. Systematic variation (SV) was regarded as significant if the 95% confidence interval (CI) excluded zero to three decimal places. Range of risk adjusted O/E event ratios apply only to those hospitals where expected number of outcome events for 1 year was ⩾5. | ||||
AMI = acute myocardial infarction; NA = not applicable as no individual facility had outcome events which numbered ⩾5. | ||||
