Affiliate Marketing Secrets

If I had to do in text citings like blah blah (name of source) how willI do it for this?
They gave me a couple of reports to read and write about and they want me to cite it, but they didnt give me the authors name. They gave me the article title and they gave me the name of the medical association the author is affiliated with and they gave me the name of the newspaper another report came from. Like, this is a report from the Mesa Medical Research Foundation— and then the report is called “Chest Pains”
How would I do the in text citations?
