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: After fertilization, the protein products of the Drosophila homeobox gene caudal (cad) accumulate in a concentration gradient spanning the anteroposterior axis of the developing embryo. Mutations in the cad gene that reduce or eliminate the gradient cause abnormal zygotic expression of at least one segmentation gene (fushi tarazu) and alter the global body pattern.

Example Input: Abstract: In an institution for the mentally retarded, a total of 13 (2.4%) susceptible employees seroconverted for hepatitis B during 539 person-years. Two of them developed acute hepatitis B; the cost of their medical care and temporary disability was $7,772. Eleven seroconverters had no elevation of serum alanine aminotransferase, and all seroconverters recovered without chronic sequelae. Nine converters acquired antibody to HBsAg alone; three of these had no client contact. Difficulty in identifying nonoccupational causes of hepatitis B infection in the institutional setting often leads to labeling of all seroconversions as occupationally acquired. Hepatitis B vaccine is recommended for client-care personnel.

Example Input: Abstract: Fluctuations of mood and psychic activation were assessed in relation to "mobile" and "immobile" periods in 18 patients with Parkinson's disease presenting typical "end-of-dose deterioration". Twelve subjects with chronic but active rheumatoid arthritis presenting increased physical disability due to severe morning joint stiffness with a repetitive pattern of mobile and immobile periods acted as controls. The overall degree of disability and its fluctuations were close enough in the two groups for fair comparison of changes in affective behaviour. Temporary immobility was accompanied by adverse changes of mood and activation, which were significantly more marked in the Parkinson's disease group than in the controls, though to a lesser extent in those Parkinson's disease patients rated depressed even in their mobile periods. The possible correlation between mood changes and fluctuations of central dopaminergic function in the Parkinson's disease patients is discussed.
