Each analysis includes a letter indicator (“manuscript” column) linking the test in the table to the analysis in the text. The link to the corresponding figure, if any, and the sample used for the test are indicated in the “figure,” and “sample,” columns, respectively. The “current” sample includes tests using data from the current work, and the previous study is indicated as Wang et al. (2014), the dependent variables for each test are listed as “data type,” and the “data structure” column indicates whether the data are normally distributed. The type of test, contrast, and the groups used for the analysis are listed in the “type of test” column. The multiple correction method is listed under “multiple comparisons correction.” the program used to perform the analysis is included under “program.” The critical value and degrees of freedom are listed for each test under “statistics.” Finally, the p value and confidence intervals are listed in the final two columns. DLPFC, dorsolateral prefrontal cortex; GC, global connectedness; LPOC, left precuneus and medial occipital cortex.
