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: A retrospective review of hospital records for 333 patients admitted to a large community teaching hospital by family physicians and family practice residents was performed to determine whether teaching programs in family practice led to a significant increase in the cost of care to patients. Three patient populations were identified for comparison: patients admitted by private family physicians when residents were not involved in patient care, patients admitted by the same family physicians while they served as attending physicians on the family practice service and allowed residents to participate in the care of their patients, and patients admitted by residents from the patient population at the Family Practice Center. After taking into account differences in case mix, an analysis of laboratory charges, radiology use, frequency of procedures, and use of consultants showed that the three groups were not different. Family practice residents managed their own patients as cost effectively as physicians in private practice, which suggests that experience alone is not necessary to develop methods of cost-efficient care. When these two groups were combined into a teaching unit, with few exceptions this efficiency was maintained. These results imply that the introduction of family practice residents into patient care does not invariably increase expenses to the patient.

Example Input: Abstract: Daylength (photoperiod) influences the rate of reproductive development in the juveniles of some photoperiodic species. Recent studies show that daylength during the prenatal period is perceived by the fetus and that this perception can profoundly influence postnatal reproductive and somatic development. Using the photoperiodic Djungarian hamster, we assessed the role of the maternal pineal gland and its hormone, melatonin, in this prenatal perception of daylength. Maternal pinealectomy eliminated the influence of prenatal photoperiod on testicular and body weights of male pups, suggesting that a product from the maternal pineal gland communicates daylength to the fetus. Infusion of the pineal hormone melatonin into pinealectomized dams for various durations during gestation mimicked the effect of varying the prenatal photoperiod on both testicular and body weights. These results indicate that pineal melatonin is involved in this novel form of communication from mother to fetus.

Example Input: Abstract: The effects of cimetidine on the healing and recurrence of duodenal ulcers and gastric ulcers were compared. The extent of the acid secreting areas was examined by the endoscopic Congo red methylene blue test. Using the extent of acid secreting areas gastric ulcers were classified into ulcers with and without extensive acid secreting areas. Duodenal ulcers were all associated with extensive acid secreting areas. The gastric acid outputs in the basal state and after maximal stimulation with gastrin were highest in duodenal ulcers, and lowest in gastric ulcers without extensive acid secreting areas. Cimetidine treatment significantly promoted the healing of duodenal ulcers and gastric ulcers with extensive acid secreting areas when compared with placebo, but not of the gastric ulcers without extensive acid secreting areas. Cimetidine also significantly diminished the recurrence of duodenal ulcers, but not gastric ulcers with and without extensive acid secreting areas. These findings indicate that in Japan cimetidine promotes the healing of duodenal and gastric ulcers associated with high gastric acid production and prevents recurrence of duodenal ulcers, but has little or no influence on the healing and recurrence of gastric ulcers associated with low acid secretion.
