Follicle and urinary hormones pairwise correlations post-altrenogest treatment before (B) a dominant follicle was identified (DOD) and after dominance was established (A) until ovulation in bottlenose dolphin as represented by pairwise linear mixed model analysis with marginal and conditional correlation coefficients (mR², cR²), respectively.

Bold values indicate a mild (r ≥ 0.1) or greater marginal correlation.

^*No large follicles were present before DOD, so the row was omitted.

aDOD, after dominance established; E1-C, estrone conjugates; E3, estriol; FSH, follicle-stimulating hormone; LH, luteinizing hormone; NA, not applicable because no large follicles were present; Pg, progestagens; PrDOD, prior to dominance; tLG: >16 mm, total large follicles; tMD: >10–16 mm, total medium follicles; tSM: >6–10 mm, total small follicles; tVSM: 3–6 mm, total very small follicles.
