Annual Publication and Major Research Directions
There were 3,907 studies on CRS and NPs between 01 /01/ 2003 and 31/ 12/ 2022, including 3,266 ”articles” and 641 ”reviews”. The number of publications on CRS and NPs steadily increased in the past two decades.
As shown in Figure 1A, this field attracted the attention of scientific researchers at an early stage. Of the studies, 27 were published in 2003. From 2003 to 2020, the number of publications increased rapidly. The publications increased by 133.3% (27 in 2003, 387 in 2020). Starting from 2020, the publication trend in the last three years (2020-2022) had been relatively stable, which may mean that the number of studies temporarily peaked.
We classified the 3907 studies on CRS and NPs (Figure 1B), and found that ”Otorhinolaryngology”, ”Immunology”, and ”Immunology” were the three primary research directions in the research.
