Comparison of final list of core concepts with initial survey and text mining results.
Given that this is the first time that a combination of text mining and survey have been used to elicit candidate core concepts, it is of interest to analyse the source of the final list of 25 terms. Nineteen of the 25 core concepts (76%) were exact matches to terms in either the text mining refined list or the survey refined list, and eight were present in both. A further eight core concepts were present in the survey list but not the text mining list and three core concepts were present in the text mining list but not the survey list (Supplementary Table 2). Six terms had no exact match in either text mining or survey list, and were derived from the merging of synonyms during the workshops between Rounds Two and Three.
