Figure 9:Individual values of cross-ApEn in six women who had their blood sampled at 7-min intervals for 24 hours. Each woman’s cross-ApEn is plotted, with a SD denoting the Monte Carlo-predicted experimental uncertainty in the cross-ApEn calculation, given the dose-dependent within-assay errors. Below each set of cross-ApEn values is a mean ± SEM for the group of six individuals. The interrupted line denotes the mean global random cross-ApEn. Lower cross-ApEn values indicate greeter pattern repetition or conditional synchrony in the point-by-point release profiles of the two hormones. From ref. (26) with permission.
