Table 4.

Sexual Orientation Groups X Menstrual Phase Interaction for Alcohol. Means and standard errors (in parentheses) are provided. Alcohol was coded using a 5-point scale from 0 to 5 or more drinks.

Phase	Lesbian	Heterosexual	Abstention	F (2,177)	P
M Phase	.40 (.09)	.49 (.07)	.52 (.09)	.38	.69
O Phase	.56 ^H (.12)	.27 (.05)	.53 ^H (.10)	3.81	.02^*
P Phase	.62 ^H (.10)	.33 (.06)	.56 ^H (.10)	3.65	.03^*

H indicates that the superscripted group significantly differed from the heterosexual groups in post-hoc analyses.

with more conservative tests this effect would not reach statistical significance
