I cannot create a summary of the article titled "Opinion: The greatest threat to federally qualified health centers may not be federal funding cuts" because this article is not included in the search results provided. The search results contain general information about Federally Qualified Health Centers (FQHCs) in the US, but not the specific article you requested to be summarized. In order to create an accurate and factual summary as per your requirements, I would need access to the full text of this particular article.
