Although not of primary interest here, we note that in the analyses reported above, the relationship of survival to age at treatment start was positive and marginally significant ( p < 0.10 for onset of clinical signs to NAP, p < 0.05 for onset of clinical signs to time of euthanasia, p < 0.10 for start of treatment to NAP, and p < 0.10 for start of treatment to time of euthanasia).
