Abstract:The Database COMAR now includes data from more than 8640 CRMs supplied by 180 producers in 24 countries. These data are divided into 8 main categories, containing up to 10 sub-categories. Quality of life as well as biological and clinical CRMs are two main categories where a great increase could be observed in the past years. These fields represent approximately 20|X% of the data records. Therefore it will be possible to gather different statistical information from these data.
