Net heat plot in the diabetes example. The area of the gray squares displays the contribution of the direct estimate in design d (shown in the column) to the network estimate in design d’ (shown in the row). The colors are associated with the change in inconsistency between direct and indirect evidence in design d’ (shown in the row) after detaching the effect of design d (shown in the column). Blue colors indicate an increase and warm colors indicate a decrease (the stronger the intensity of the color, the stronger the change). The two contrasts of the three-armed study with design plac:acar:metf are marked with ∗.
