Number of signals assessed by the PRAC in last 6 years. Signals may be assessed (and thus counted in the chart) in >1 year. Although the graph looks like there were a high number of signals in 2012, this is because there were ongoing safety issues before the PRAC was formally established, which were ongoing and fed into the PRAC. Therefore, 2013 would be a better considered baseline.
