“…The VMDB data consist of data from dogs that were seen at veterinary teaching hospitals. Patients at these tertiary care facilities are more likely to present with cancers and rare or serious diseases (Bartlett, Van Buren, Neterer & Zhou, 2010). Also, the VMDB age data are collapsed into bins.…”

“…Because the VMDB represents Veterinary Teaching Hospital patients, it is subject to referral bias (Bartlett et al., 2010), meaning these patients likely exhibit more severe, complicated, or unusual diseases that are seen in the canine population at large, and average income of clients might be higher than that for all dog owners. By contrast, the VetCompass dataset is comprised of complete clinical records from primary care veterinary practices, and as such might provide a better representation of the canine population as a whole.…”

“…However, as data typically exist as separate records, it can be difficult and time-consuming to collate. In addition, differences in documentation practices, investigative and treatment protocols, as well as coding of cases among centres can limit comparison of cases (Bartlett and others 2010). …”

“…Neste sentido, o conhecimento, por parte do pesquisador, de aspectos marginais aos dados per se é fundamental para a adequada utilização dos mesmos (Todeschini 2010). A busca de soluções para essas limitações passa pelo conhecimento das bases teóricas do universo de existência e de obtenção dos dados, bem como o adequado tratamento estatístico destes para minimização de efeitos indesejados resultantes do distanciamento existente entre seu objetivo primário e aquele proposto pelo analista (Dohoo et al 2003, Lattin et al 2003, Bartlett et al 2010, Todeschini 2010. Uma limitação frequentemente verificada em séries de dados secundários é a ocorrência de dados faltantes em determinadas variáveis, cuja presença pode representar dificuldades para a análise, como: perda de informações contidas nestes elementos faltantes e complicação no tratamento dos dados (Barnard & Meng 1999, Schaefer 1999.…”
