Figure 2

Annual prevalence of preterm birth in Western Australia for the period 1980–2015. Lowess: the local linear smooth plot was generated using Cleveland’s tricube weighting function with a bandwidth of 0.8 (Cleveland, W. S. 1979. Robust locally weighted regression and smoothing scatterplots. Journal of the American Statistical Association 74: 829–836).
