|---|---|---|---|---|---|
| Placebo | 57/102 | 55.9 | |||
| Desvenlafaxine low exposure | 59/105 | 56.2 | 0.97 | 0.56, 1.69 | 0.925 |

CGI-I scored as 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; 7, very much worse; 1 patient in each desvenlafaxine group scored 5 at week 8 and no patient scored 6 or 7 at week 8.
CGI-I response was defined as CGI-I score of 1 (very much improved) or 2 (much improved).
