Suicidality and aggression during antidepressant treatment: systematic review and meta-analyses based on clinical study reports

Re Marc Stone's response. Would it not be more dignified and compassionate to refer to people who have committed suicide as 'people/individuals' rather than 'subjects' of a study? It would be interesting to know how Ethics approval is gained for studies as sensitive as this especially when the outcome is potentially that some will die..... For example, how do people become randomised to different treatments? Are they giving consent to participate?
