## Figure 1.
Network design and hat matrix of an illustrative network meta-analysis. In a), the network design of an illustrative example is given: six treatments and eight
different observed designs based on two-armed studies. The nodes correspond to the
treatments, and the edges show which treatments are directly compared. The thickness
of an edge represents the inverse standard error
, which is equal one for all designs. In b), the resulting hat matrix at the design level is given in percent, which indicates
the contribution of the direct estimate in design d (shown in the column) to the network estimate in design d’ (shown in the row). In addition, the absolute values of the matrix elements are
visualized by the area of the gray squares.
