↵a Stepwise Poisson regression, dependent variable: observed admission count.
↵b Stroke 8: Percentage of patients with TIA or stroke whose last measured total cholesterol is ≤5 mmol/l.
↵c Patient Experience 8: score for ability to book an appointment with a GP more than 2 days ahead.
IMD = Index of Multiple Deprivation. IRR = incidence rate ration. SE = standard error. TIA = transient ischaemic attack.
