Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.

Example Input: Abstract: Chancroid, a disappearing disease in the United States, was reintroduced into the country in 1980 by immigrants from the Caribbean, Mexico, and Southeast Asia. Point epidemics resulted, each of them associated with prostitution. During the 4-month period between March 1 to June 30, 1985, forty-five patients were diagnosed and treated in Massachusetts, thirty-seven from Boston alone. By means of these case records, the morphologic characteristics, laboratory diagnosis, and treatment regimens are described.
Question: Does the abstract contain any numerical data?
Example Output: Yes

Example Input: Abstract: To assess whether continuous arteriovenous ultrafiltration (CAVU) might constitute a useful alternative to hemodialysis in the management of patients with advanced liver failure, we carried out CAVU in 3 patients with decompensated Laennec's cirrhosis. CAVU was utilized in two patients with acute renal failure and pulmonary edema to stabilize renal function and facilitate administration of large amounts of fluid. In the third case, CAVU was successfully utilized to mobilize fluid in a patient refractory to conventional diuretic regimens. We conclude that CAVU may constitute an appropriate alternative to traditional hemodialysis in patients with advanced liver disease and renal functional impairment.

Example Input: Abstract: Acute epiglottitis in the adult is uncommon. This case reports a young man with acute epiglottitis secondary to a Bacteroides melanogenicus supraglottic abscess. This pathogen has not been previously described as being causitive of epiglottitis.
