frequent

Hi,

""Clinical nutrition" (42.1%) and "techniques and methods" (3.4%) were the most and the least frequent topics respectively. The most frequent articles in study design were descriptives then trials."


In an article, the researchers are trying to evaluate the articles published during a specific period of time by comparing their "study design, publication type, and subject headings". The above sentences are the results reported by them. I want to know if the term "frequent" fits the sentence and if there is any other error.

Thank you

For preference I would use the word " common " in the sense of frequent occurrence.

In a research report I would not use common here. The researchers have been measuring the frequency of occurrence of topics. Frequent is being used with a specific meaning which will be clearly understood by the intended readership.
