Science, rhetoric and the causality of adverse events.

This paper outlines aspects of the interface between law and science in the domain of treatment induced injury, using examples drawn from litigation on SSRIs. In the face of claims that randomized controlled trials provide uniquely appropriate evidence and that there should be a statistically significant doubling of the risks on treatment, the examples used demonstrate that the methods of assessing the possibility of causal links between treatment and injuries must necessarily be tailored to both the injury and the treatment.
