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: Cryosurgery is now a widely accepted modality for the treatment of basal cell carcinomas. This article presents a practical approach to using cryosurgery for this purpose in the dermatologist's office. Understanding the cryobiologic basis of cryosurgery is a prerequisite. Aspects of treatment covered include selection and use of appropriate equipment, indications and contraindications for specific tumors, preoperative preparation, various treatment technics with clinical and instrumental depth-dose monitoring, postoperative care, cure rate, and cosmetic and functional end results. The overall results obtained by cryosurgery compare favorably with those obtained by other modalities. Cryosurgery is the treatment of choice for some basal cell carcinomas and a satisfactory alternate treatment for others.

Example Input: Abstract: In search of a practical biochemical test that will reflect hepatic steatosis, we assessed the significance of serum cholinesterase activity in 48 patients with nonalcoholic fatty liver, 16 obese subjects without fatty liver, 30 cases of chronic persistent hepatitis, 38 cases of chronic active hepatitis, and 20 cases of liver cirrhosis. Increased cholinesterase activity was observed in nonobese as well as obese patients with fatty liver, whereas obese subjects without fatty liver showed levels in the upper normal range. When we set a cutoff level above the upper normal limit, half of the patients with fatty liver showed values above it, with only a few overlaps with other patients. When obese patients with fatty liver took a low-caloric diet, cholinesterase activity decreased, clearly reflecting improvement of hepatic steatosis. Thus, measurement of cholinesterase activity is of diagnostic value and an alternative to computed tomography in hepatic steatosis, and will provide a practical measure for the assessment of effects during follow-up.

Example Input: Abstract: Localized regions of mineralization were found in confluent cultures of rabbit marrow fibroblastic cells. The mineralized tissue developed within clusters of giant fat cells in the spaces between the cells. Investigations with light and electron microscopy demonstrated that in these sites there was some differentiation of the fibroblastic cells in an osteogenic direction, shown by changes to more polygonal shapes, and the synthesis of well-banded collagen similar to that found in bone tissue. Differentiation may be due, in part, to increased cell density in a confined space. Growth of the mineralized tissue was observed in the living cultures with a fluorescence microscope. Electron probe microanalysis confirmed that the mineral formed was hydroxyapatite. Initiating sites of mineralization included membranous vesicular bodies, lipid, and products of cellular degeneration. Once initiated, mineralization appeared to spread rapidly into adjacent collagenous and other structures, suggesting the appearance of a mixture of skeletal-type and dystrophic mineralization.
