Notes on process:

- used terms in Clegg codelist to search on "term" and identify additional codes 
- finally read in Angel Wong and CWG Thyroid disease codelist and included any additional terms (n=20) 

Notes on inclusion/exclusion criteria: 
- included historic ("history of") codes as trying to capture frailty as a state rather than incidence of components
- excluded "family history" codes
