Remarks

The same symptoms were written on different pages with different values To differentiate an (Roman) order number was addited on symptoms that were mentioned more times. Because of this unclear situation, only absolute frequencies of the values were given. Value "Unknown" was left out, because of its frequency: it is unclear what it means.
