Individual reports cannot usually answer whether there is a possible link between the medical product and the reported suspected adverse reactions. The collected science is needed to determine whether or not there is a risk increase for a particular suspected adverse reaction. Because reported suspected adverse reactions do not need to be caused by the medical product but may be due to other factors.
