Linear regression to determine the relationship between F-wave latency and limb length in control dogs

Minimal latencies of F waves were determined for the ulnar and sciatic-tibial nerves in 17 dogs of various breeds, weighing between 8 to 25 kg. A linear regression model was fitted to the data (r = 0.78 and 0.87, respectively), so that latencies could be predicted despite the large variation in limb lengths among different breeds of dogs.
