We specifically reconstructed and analyzed two GQI indices of GQI, GFA and NQA, by DSI Studio. ANCOVA was performed to observe the differences between the three groups. Then, post hoc two-sample t-tests were performed to assess two indices (GFA and NQA values) among brain regions for further evaluation among the three groups using SPM. A false discovery rate (FDR)-corrected p value of < 0.05 was considered to be statistically significant.
