Reported when the standard deviation is between 50 and 120% of the mean.

Lameness measure is within reference range. 

If asymmetry of head or pelvic movement is within reference range and the variability is very low, “weak or moderate evidence” of “very mild asymmetry” may be reported. Note that this is sub-threshold asymmetry, reported only as an alert to the veterinarian that very mild asymmetry with low variability is present. Only the veterinarian can confirm any asymmetry, above or below established reference ranges, as clinically significant lameness.

Reported when the standard deviation is less than 50% of the mean Diff Min head (since Diff Min Head determines the side of forelimb lameness, it is the more important measure to assess for variability); or Mean Diff Min and/or Diff Max pelvis. 

Reported when the standard deviation is greater than 120% of the mean.
