aIncidence rates are presented per 100,000 inhabitants
b33 remaining patients were treated in a hospital setting other than UMC, top-clinical or general hospital (i.e. private clinic)
cTop-clinical centers are non-academic hospitals that provide more complex care than general hospitals and usually have an important role in training doctors and in conducting scientific research
