† The percentage change is from 1981–84 to 1996–99, estimated by fitting a ordinary least squares regression (unweighted) to the SIIs to work out the regressionestimated change in the SII over time, the regression estimated value for 1981–84, and hence the percentage change. ‡ We conducted ordinary least squares regression of the SII on census year (weighted by the inverse of the variance of the SII), and used the pvalue for the census year term as our pvalue for trend.
