Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Supportive Care (vitamin B6)

Arm Description

Participants receive vitamin B6 PO daily for 12 weeks.

Outcomes

Primary Outcome Measures

Median change in response to 10-point hot flash scale (1 = hot flash is not bothersome, 10 = hot flash is Most Severe)
For the primary analysis, the difference in the median response to the 10-point hot flash scale between 8-week post-treatment and pre-treatment responses will be computed with the corresponding 95% percent confidence interval. The primary null hypothesis will be tested using a two-sided Wilcoxon Signed-Rank Test with alpha=0.05.

Secondary Outcome Measures

Median change in response to 10-point hot flash scale (1 = hot flash is not bothersome, 10 = hot flash is Most Severe)
The same approach will be used for the secondary analysis of 12-week post-treatment responses in comparison to the pre-treatment responses.
