What Am I Doing Wrong … bibliography entries not being included

[Trevor Jenkins]

When I View my document ⌘-R pdflatex shouts that there are no citations! I have added the relevant BibTeX file using Insert > List/TOC > Bib(la)Tex Bibliography picking a local .bib file and then added a citation using Insert > Citation followed by Adding a specific citation. (It appears in a sidenote entry as I have tuftepaper as my document class.) 

Pdflatex’s error message is 

BibTeX error: I found no \citation commands---while reading file Statins.aux

It makes no difference what Citation Style I select when adding the citation. I have had this working before (on a now dead machine) but cannot for the life me work out what I am doing wrong.

Operating System: macOS 12.3.1 (Monterey)
Processor: M1
LyX version: 2.3.6.2
Python: 3.10.4 (freshly (re)installed)
Document class: tuftepaper
     with custom options: justified,a4paper,sidenote=raggedright,marginnote=raggedright,nobib
     that latter because I want to suppress the final bibliography listing and was fine in my previous not that it suppressed the bibliography


Regards, Trevor.
