  1. For the evaluation of bottom-up standardization in the pragmatic MDR proof of concept, we used search queries for six different medical concepts (column 2) taken from four different groups (column 1). The entries in column 2 were used to query the pragmatic MDR and the resulting top three search results ranked by frequency-based scoring along with their number of occurrences (Occ) were determined (columns 3 and 4). The last two columns show the same results for a relaxed equivalence definition that only required the ODM question element in lower case to coincide
