Here is the tile of a journal article: https://annals.org/aim/article-abstract/2724039/recognizing-potential-overdiagnosis-high-sensitivity-cardiac-troponin-assays-example

"Recognizing the Potential for Overdiagnosis: Are High-Sensitivity Cardiac Troponin Assays an Example?"

Hmm. I think it should be:

"Recognizing the Potential for Overdiagnosis: Is a High-Sensitivity Cardiac Troponin Assay an Example?"

The issue, of course, concerns the implications of a high-sensitivity assay.



  • If you get rid of that "High-Sensitivity Cardiac Troponin" mumbo-jumbo and ask both: Are assays valuable? Is an assay valuable? I think you'll see they're both right. I don't know what the paper title intends. The matter is about whether the title is supposed to mean one assay or multiple assays. – Zebrafish Feb 11 at 19:00

    In English, the subject and the complement of the verb is don't need to have the same plurality. – Peter Shor Feb 11 at 19:04
  • @PeterShor You mean to say "Is your cars large?" is OK? – Zebrafish Feb 11 at 19:05
  • No, I mean to say his cars are his passion is OK. The verb has to agree with the subject, but they don't need to agree with the complement. – Peter Shor Feb 11 at 19:08
  • @PeterShor Oh I see, you're saying in their example both "Are assays an example?" and "Are assays examples?" are both right. – Zebrafish Feb 11 at 19:11

Your version and the given title are both correct. Not knowing this medical term, I can only say that the person who is writing the paper is emphasizing the repeated occurrence cardiac assays.
