P-values denote the tail area in a two-tailed Wald statistic (z value) test for the hypothesis that the associated model coefficient is 0 (and hence is unimportant when using that follicle diameter to predict number of embryos and Grade 1 embryos). Hence, a significantly important follicle diameter is expected to have a significantly low P-value. Follicle diameter significance levels are labeled *P < 0.05, **P < 0.01, and ***P < 0.001.
