From Kergosien, D. H., barnhart, M. D., Kees, C E., Danielson, B. G., Brourman, J. D., Dehoff, W. D., Schertel, E. R. (2004), "Radiographic and Clinical Changes of the Tibial Tuberosity after Tibial Plateau Leveling Osteomtomy," Veterinary Surgery, 468-474.
186 dogs had 219 Tibial Plateau Leveling Osteotomy (TPLO) surgeries. The 0-1 response variable lucency is whether radiograhic changes were seen in the re-evaluation radiographs before starting rehabilitation. The logistic regression analysis ignored possible correlation due to surgeries on the same dog.
In the text file above, the variables are named
