"The UPMC Depression Prevention Program seeks men and women, ages 18 to 60, to participate in a research study examining the effectiveness of an FDA-approved antidepressant for major depression. If interested, call Traci Salopek at 412-624-4444." - this is what I found when searching for this number. The above number called my cell phone.
Called my cell phone three consecutive times without leaving a voicemail. I picked it up on the third call (was trying to sleep after working night shift), they asked for someone I don't know. Told the caller wrong number and hung up.
