Fig. 4. Duration of different agonistic levels per fight (A,B) and probabilities
(P) of urine release at these levels (C,D) in winners (A,C) and
losers (B,D). Values are means +1 S.E.M. for 39 fights. Asterisks denote
significant differences with respect to the mean probability over all
agonistic levels (*P<0.05,
**P<0.01; logistic regression analysis). Probabilities
at level 0 and 1 are generally lower, while those of levels 3-5 are higher,
than the mean probability of urine release as estimated by the logistic model.
At levels -2 and -1, probabilities are smaller than the mean only in
losers.
