Fig. 3From: The unrecognized role of fidelity in effectiveness-implementation hybrid trials: simulation study and guidance for implementation researchersEstimated power for parallel and stepped-wedge CRT for several fidelity patternsThe fidelity patterns are described by their start and end value (fidelity in % indicated by colour) and the different slopes of fidelity increase (slow, linear, fast) with in-between values. Each individual dot represents one particular fidelity pattern (i.e. specific start/end value and slope). All dots connected with a coloured line have the same start and end value but the slope of the fidelity increase is varying from fast (left) to slow (right) (Fig. 2B). The coloured areas comprise all fidelity patterns with the same start value, i.e. 40,60 or 80%. The single cross in the upper left corner represents 100% fidelity from the startBack to article page
