Background: The evidence associating consumption of dairy products and risk of MS is contradictory and inconclusive.
Objective: To test associations between dairy consumption and the likelihood of a first clinical diagnosis of central nervous system demyelination (FCD), a common precursor to MS.
Methods: We used data from the 2003-2006 Ausimmune Study, a population-based Australian, multicentre, matched case-control study (272 cases, 519 controls).
