Fig. 3. (A) Plasma vitellogenin (VTG) and (B) very-low-density lipoprotein (VLDL) levels measured at pre-, mid- and post-treatment in estradiol (E₂)-treated (filled bars) and sham groups (open bars). Values are means + S.E.M. Comparisons were made between E₂ and sham treatment groups at pre-, mid- and post-treatment. ^*P<0.05, ^**P<0.005, ^***P<0.0005. See text for statistics and within-treatment-group differences.
