This retrospective study of cats aged ≥10 years, referred to a single UK veterinary teaching hospital (2006) (2007) (2008) (2009) (2010) (2011) (2012) (2013) (2014) , used electronic patient records to obtain owner-reported data regarding breed, coat colour, age and sex, and clinical data to classify cats as hyperthyroid/euthyroid. Bayesian multivariable logistic regression was used to evaluate breed, age and sex as risk factors for hyperthyroid status in all the cats (purebred and non-purebred). To avoid interactions with coat length or colour in purebreds, the effect of coat colour/pattern, colour dilution, base pigment, white markings and hair length were assessed only in non-purebred cats in a separate analysis. Variables with P < 0.2 in univariate analyses were evaluated in multivariable models, with final variables significant at P ≤ 0.05. Risk factors are quantified as odds ratio ((OR) P-value).
