  1. aH: Transthyretin > 0.31 g/L; L: Transthyretin ≤ 0.31 g/L.
  2. Age was adjusted for in all analyses while adjustment for sex was applied only in analyses of total samples. 'Unexposed' were those with non-use and the quartile with the lowest overall use of mobile telephones and DECT (≤446 hours). Persons with missing information about use of wireless telephones were excluded from the analysis.
