NC, normal cycling; OC, oral contraceptive users; E2, estradiol; VMS, Wechsler memory scale.

^aUnbalanced design.

^bComposite score consisting of Shepard Metzler, 3D clocks, point location, and a test of perceptual closure was reported.

^cComposite score of the three tests were used for statistical analyses, a polynomal correlation with E2 was also reported.

^dSubjects were grouped according to saliva estradiol concentrations, regardless if tests had been made in the follicular or luteal phase.
