What is being measured
The primary outcome is the main question the study is designed to answer.
The change in MADRS total score from baseline
There are a total of 10 projects in Montgomery-Asberg Depression Rating Scale（MADRS）, each with a 7-point scoring system ranging from 0 to 6 points. The higher the score, the more severe the degree of depression.
Measured: 8 weeks
Secondary outcomes (11)
The change in HAMD-17 total score from baseline
There are a total of 17 projects in Hamilton Depression Scale-17（HAMD-17）. Scores are distributed on a scale of 0 to 53. A score above 24 indicates severe depression, a score of 17 indicates moderate depression, and a score below 7 indicates no depressive symptoms.
Measured: 8 weeks
The effective rate of MADRS
The effective definition of MADRS is that the reduction rate of MADRS score relative to baseline is ≥ 50%
Measured: 8 weeks
The effective rate of HAMD-17
The effective definition of HAMD-17 is that the reduction rate of HAMD-17 score relative to baseline is ≥ 50%.
Measured: 8 weeks
The response rate of MADRS
The response definition of MADRS is that the score ≤ 12 points.
Measured: 8 weeks
The response rate of HAMD-17
he response definition of HAMD-17 is that the score ≤ 7 points.
Measured: 8 weeks
The change in MADRS Single item score from baseline
Each single item has a 7-point scoring system ranging from 0 to 6 points. The higher the score, the more severe the degree of depression.
Measured: 8 weeks
The change in HAMD-17 factor score from baseline
- Items scored 0-4 (5-point scale, 8 items) Depressed mood, feelings of guilt, suicide, work and interests, retardation, agitation, psychic anxiety, somatic anxiety
- Items scored 0-2 (3-point scale, 9 items) Difficulty falling asleep, insomnia during sleep, early awakening, gastrointestinal symptoms, general somatic symptoms, genital symptoms, hypochondriasis, weight loss, insight. The higher the score, the more severe the degree of depression.
Measured: 8 weeks
The change in CGI-S total score from baseline
Perform the Clinical Global Impression Scale (CGI-S) score from Visit 1 to Visit 7,The highest score is 7 points, and the higher the score, the more severe the condition will be.
Measured: 8 weeks
Proportion of participants with a CGI-S score of 1/2
Perform the Clinical Global Impression Scale (CGI-I) score from Visit 3 to Visit 7.The highest score is 7 points, and the higher the score, the more severe the condition will be.
Measured: 8 weeks
Proportion of CGI-I Scores on the Clinical Global Impression Scale
Perform the Clinical Global Impression Scale (CGI-I) score from Visit 3 to Visit 7.The highest score is 7 points, and the higher the score, the more severe the condition will be.
Measured: 8 weeks
The change in HAMA total score from baseline
There are a total of 14 projects in Hamilton Scale（HAMA）.The total score ranges from a minimum of 0 to a maximum of 56. The higher the score, the more severe the anxiety.
Measured: 8 weeks
