Considering that proper reference is provided (journal, author name, date etc.), is copying exact numbers from published scientific articles could be considered plagiarism or copyright infringement?
For example, there is a research called "Dancing can reverse the signs of aging in the brain". I need to cite in my own research some data from it, including how many there were participants, their gender (how many men/women), age and BMI. There are some tables as well, from which I intend to take some baseline numbers. As a result, I'm making my own conclusions (words or sentences are not copied, only numbers).
