Analysis of the effect of experimental treatments on resistance to hypoxia at the juvenile stage by a Cox proportional hazards model. (The reduced model resulting from backward elimination is presented. For each covariate, the following elements are provided: its effect estimate α together with its s.e. (α) and the corresponding multiplicative effect exp (α) on instantaneous hazard rate in the reduced model; the χ2 statistic (with 1 d.f. for all tests) and the resulting p-value for the type II test from the complete model. T, larval rearing temperature (continuous); L, juvenile dietary lipid content (continuous).)
