Figure 4.

The graph with DOT layout after reduction by Meth 3 and Meth 4 from the physicians’ data set with T_a=75 and T_r=0.4 (the mnemonics are likely too small to be read, but are unimportant for the purpose of illustrating differences to the next graph). Areas of the graph outlined with dashed lines are sections that differ from the nurses’ graph (see text for details).

Note: all the colors of the nodes, colors of the links, arrows’ directions, sizes and colors represent different meanings, node colors: AF > 200, red; 200≥AF>100, pink; 100≥AF>50, light blue. For arrows: RV=1, red, double arrow head and backwards; 1>RV≥ 0.9, orange, double arrow head and backwards; 0.9>RV≥0.7 green, double arrow head and backwards; 0.7>RV≥0.5, brown, double arrow head and backwards; 0.5>RV≥0.3, black, double arrow head and backwards; RV <0.3, black, single arrow head and forwards.
