Recent Achievements And Directions Of CRM Producers

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.
