Q

Smith; Chronology of Hip Dysplasia Development in a Cohort of 48 Labrador Retrievers Followed for Life. Vet Surg. 2012. - DI predicted how many (all DI > 0.35) would get OA due to dysplasia?
Whereas OFA @ 2 yrs predicted what %?
Radiographic and Histopath

A
  • DI predicted all of them (DI > 0.35) and 98% over all for both radiographic and histo.
    Whereas OFA @ 2 yrs predicted less than half (45% negative predictive value for rad OA and 8% for histo)

Q

Smith; Chronology of Hip Dysplasia Development in a Cohort of 48 Labrador Retrievers Followed for Life. Vet Surg. 2012
Was DI shown to be influenced by environmental factors in this study?
Was their a diff in DI between the diet fed and control fed dogs?

A

no, because DI was only measured at 2 years,
