**Table A1.** Methods and strategies of studying CI in policymaking used in each particular research area group (RAG), compared to all the reviewed studies. NoS stands for number of studies, in which the particular research method is used; method usage (MU) indicates the percentage of studies in which the research method was used; DPP stands for the difference in percentage points between MU in this group and MU in all the reviewed studies; MAE stands for the mean absolute error for the analyzed group. The assignment of particular methods and strategies to the labels numbered from 1 to 15 is described in Table 2.


**Table A2.** Methods and strategies of studying CI in policymaking used in the most influential studies, compared to all reviewed studies. NoS stands for the number of studies in which the particular research method was used; method usage (MU) stands for the percentage of studies in which the research method was used; DPP stands for the difference in percentage points between MU in this group and MU in all reviewed studies; MAE stands for the mean absolute error for the analyzed group. The assignment of particular methods and strategies to the labels numbered from 1 to 15 is described in Table 2.


**Table A3.** Methods and strategies of studying CI in policymaking used in the subgroups of studies based on selected topics of interest. NoS stands for number of studies in which the particular research method is used; method usage (MU) stands for the percentage of studies in which the research method was used; DPP stands for the difference in percentage points between MU in this group and MU in all reviewed studies; MAE stands for the mean absolute error for the analyzed group. The assignment of particular methods and strategies to the labels numbered from 1 to 15 is described in Table 2.
