Distributions of 21 prefecture-level CSSIs using different nonfamine years. Prefamine births: 1953 to 1957; postfamine births: 1963 to 1967. Box plots show the median and IQR of both CSSIs. Data source: 2000 national census for Sichuan Province (6).

Scatterplot of CSSI and IRR of F1 across prefectures. Each prefecture is represented by a dot. The size of the dot is proportional to the inverse variance of the estimated IRR of each prefecture. The lines represent the metaregression fits, and the shaded areas represent the 95% CIs.
