Abnormal Vaginal Bleeding

Variant 1: Postmenopausal vaginal bleeding. First study. (Endometrial sampling may also be performed initially followed by imaging if results are inconclusive or symptoms persist despite negative findings.)

Final Tabulations:
A histogram of the number of panel members who rated the recommendation as noted in the column heading (ie, 1, 2, 3, …etc.)
Disagree:
The variation of the individual ratings from the median rating indicates panel disagreement on the final recommendation.
References:
Lists the references associated with the recommendation
SQ:
Study Quality (1, 2, 3, 4, Good M or Inadequate M) of the references listed.
RRL:
