Table 4

- and r²-values for the models obtained from fitting the generalisable model to the point prevalence data sets from Futatsuka and Ueno [26] using equation (4) with the parameter values from Table 1 for the 4th-order and the time-dependent exposure factor. The time-dependent exposure factors are determined from the corresponding period prevalence data (see Tab. 3). The 95-percentile confidence intervals for are given in brackets. The bold coefficients are the ones used in the following analyses.
