This study describes an approach for the use of a specific type of qualitative evidence synthesis in the matrix approach, a mixed studies reviewing method. The matrix approach compares quantitative and qualitative data on the review level by juxtaposing concrete recommendations from the qualitative evidence synthesis against interventions in primary quantitative studies. However, types of qualitative evidence syntheses that are associated with theory building generate theoretical models instead of recommendations. Therefore, the output from these types of qualitative evidence syntheses cannot directly be used for the matrix approach but requires transformation. This approach allows for the transformation of these types of output.

用现实主义的观点将理论从定性证据综合到定量研究联系起来：拓宽矩阵法。

这项研究描述了一种在矩阵方法中使用特定类型的定性证据综合的方法，一种混合​​研究综述方法。矩阵方法通过将来自定性证据综合的具体建议与主要定量研究中的干预并置，在审查级别比较定量和定性数据。但是，与理论构建相关的定性证据合成类型会生成理论模型，而不是建议模型。因此，这些类型的定性证据合成的输出不能直接用于矩阵方法，而需要转换。这种方法可以转换这些类型的输出。
