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: It is clear that some synovial inflammation occurs in joints affected by osteoarthritis (OA) and it is well recognized that many patients with OA experience a decrease in pain and joint stiffness following administration of salicylates or other nonsteroidal antiinflammatory drugs (NSAIDs). However, neither the extent to which synovitis contributes to the cartilage breakdown in OA nor the effects of chronic administration of NSAIDs on the natural history of OA in humans is known. Recent studies indicate that several NSAIDs, including salicylates, suppress proteoglycan synthesis in articular cartilage in vitro. The effect on OA cartilage is more marked than that on normal cartilage. Other studies show that salicylate feeding may suppress proteoglycan metabolism in degenerating cartilage in vivo, aggravating the decrease in proteoglycan content caused by the disease itself. However, no effect of salicylates on normal articular cartilage has been observed in vivo. In damaged cartilage the magnitude of NSAID-induced suppression of proteoglycan metabolism appears to be related inversely to the proteoglycan content of the tissue. In addition, the NSAIDs used in treatment of arthritis today may differ with respect to their in vivo effects on articular cartilage metabolism due, in part, to differences between the molar concentrations of these drugs in synovial fluid.

Example Input: Abstract: Fifty ragweed-sensitive subjects were each administered a course of 12 injections of polyethylene glycol-modified ragweed extract. To investigate the effect of two treatment regimens, subjects were paired according to their skin sensitivity to ragweed extract and the severity of their rhinoconjunctivitis the previous year. One of each pair was randomly allocated to receive injections at weekly intervals, and the other subject was to receive injections daily until a local or systemic adverse reaction occurred and then to switch to a weekly schedule for the rest of the course. Blood was obtained immediately before each injection and at the end of the study to examine the rates of change of ragweed-specific IgE and IgG antibody levels and to evaluate whether these or other variables could be used to predict the occurrence of adverse reactions. Immediate reactions were minimal in both groups, but more late reactions occurred in subjects receiving the modified rush regimen; therefore, although the total number of injections received by the two groups was similar, the total dose of protein injected in the rush group was only half that achieved in the weekly group. Treatment induced increases in ragweed-specific IgE and IgG antibodies in both groups; the increase in IgE was similar in the two groups, but the increase in IgG was higher in the weekly group. There was a marked decrease in skin sensitivity to ragweed extract after treatment that was directly related to the IgG antibody response, and therefore, these changes were greater in the weekly group.(ABSTRACT TRUNCATED AT 250 WORDS)

Example Input: Abstract: Identifying the parathyroid glands is of fundamental importance in thyroid and parathyroid surgery. We found that intravenous infusion of methylene blue was beneficial in intraoperative identification of the parathyroid glands in patients undergoing surgery for hyperparathyroidism as well as total and bilateral subtotal thyroidectomy. The technique is safe and easy to use, and it clearly reduces the operative time. We suggest that it be used routinely in thyroid and parathyroid surgery.
