FIGURE 4.
The subjects of response or remission at 8 weeks treatment in the guided group and the unguided group. Response to therapy was defined as the RR of HAMD-17 by ≥ 50%. Remission was defined as the final HAMD-17 score ≤ 7 at the end of the 8-week treatment. The two histogram bars on the left represent the treatment response of two groups and the two right represent treatment remission of two groups. P-values on the left and right represent the comparison of response rates and remission rates respectively, between two groups. P-values are derived using χ2 tests. HAMD-17 = 17-item Hamilton depression scale; RR, reduction ratio.
