Percentage change with 95% confidence interval of hospital admissions for total and cause-special cardiovascular disease associated with a 1 mg/m3 increase in daily CO concentrations with varying lag patterns. Data are percentage changes (%) with 95% confidence intervals. Lag 0 = current day. Lag 1 = previous 1 day. Lag 2 = previous 2 days. Lag 3 = previous 3 days. Lag 4 = previous 4 days. Lag 5 = previous 5 days. Lag 0–1 = 2-days moving average of lag 0 - lag 1. Lag 0–3 = 4-days moving average of lag 0 - lag 4. Lag 0–5 = 6-days moving average of lag 0 - lag 5
