Figure 4

Comparison of unlagged predicted values for the smoothing spline component of the fitted Poisson regression models, representing medium to long-term trends of the Emergency Department ('ED') and laboratory ('Lab') series by year. Y-axis scales are chosen to give a similar range for both ED and laboratory series in each year to allow comparison of trend rather than absolute magnitude of the series over time.
