Fig. 1: Each subgroup is represented by a dot in the central plot where the position is determined by the subgroup’s sample size (horizontal axis) and statistical measure of the treatment effect (vertical axis).

The blue dots in the plot and numerical tabulated results below the plot for the factor “mother’s age at childbirth” appear after clicking the “Factorial Context” tab for a previously actively selected subgroup (orange). While the factorial context with blue dots highlights the individual levels of the factor “mother’s age at childbirth”, the yellow complementary group highlights the subgroup of all combined subjects excluding the subjects belonging to the selected (orange) subgroup. The interaction plot (line plot) at the right can be extended with another factor if desired.
