Table 1. Result of Cox proportionate hazard test for comparing the approach of adults, juveniles and pups with their latencies.

Covariate	Hazard ratio	Lower CL	Upper CL	p
Juveniles	0.57	0.29	1.10	0.09
Pup	2.08	1.24	3.49	0.005

Hazard ratio depicts how many times the probability of approaching or not approaching the set-up of the covariates are compared to the adults. The lower and upper CL (confidence limit) gives the confidence interval of the hazard ratio.
