Patients with sino-nasal complaints presenting to an allergists or otolaryngologists practice frequently are diagnosed with conditions including allergic rhinitis (AR) and chronic rhinosinusitis (CRS). Furthermore, patients with chronic rhinosinusitis are pheotypically classified as CRS with and without nasal polyposis (CRWwNP and CRSsNP, repspectively). There is an intuitive sense that atopy is an underlying etiologic factor in the development of CRS, particularly CRSwNP. Certainly, many patients with CRS will have atopy.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
