Input: Abstract: The technique of alcohol injection in the vulva is reserved for the attempted relief of pruritus vulvae in patients who have failed to respond to a conscientious trial of medical therapy. The procedure is time-consuming, but the operative time can be shortened significantly if a transparent adhesive drape with a grid drawn on it is applied to the vulva before injection.
Question: Does the abstract contain any numerical data?
Output:
No
