Summary of clustering results for the studied population

Each individual is represented by a colored circle. Red circles represent those who received placebo, and blue circles represent those who received ondansetron. Data were plotted assuming three parental populations, and each circle shows the mean estimated ancestry for an individual in the sample. The differences between the placebo and ondansetron groups in mean proportions of ancestry for each of the three parental populations were not significant.
