Quality assessment tool of original fMRI studies

Category 1: sample characteristics (10)
1Participants were enrolled with clearly described standardised diagnostic criteria (2).
2Comprehensive demographic data with comparable baseline between groups (1).
3Inclusion and exclusion criteria are reasonable, taking into account the possible affecting factors (2).
4Cognitive outcomes were reported in detail (3).
5Sample size >10 in each group (2).
Category 2: methodology and reporting (10)
6The machine model and field strength of the MRI scanner is reported (1).
7A clear description of the study procedure and quality control, includes the methods to ensure that the subjects are in a ‘resting state’ (2).
8At least 5 minutes of resting state acquisition (2).
9The report of scanning parameters is comprehensive and reasonable, and the quality control method of image scanning is reported (1).
10Detailed description of software and toolkits used (1).
11Results were applied and reported in original literature, including peak coordinate and cluster size of each brain region (1).
12Multiple comparison corrections were applied and reported in the original literature (1).
13Conclusions were consistent with the results obtained and the limitations were discussed (1).
