TASK DEFINITION: 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.
PROBLEM: Abstract: A reverse hemolytic plaque assay for detecting casein release from individual mammary cells in culture was developed as a bioassay for PRL. Treatment with rat PRL caused dose-related increases in the percentage of mammary cells that released casein and the average size of casein plaques that formed. The assay exhibited exquisite sensitivity (156 fg rat PRL per assay slide) and could be used to evaluate the biopotency of PRL released from individual cells. By combining this "plaque bioassay" with a standard plaque assay for measuring the secretion of immunoreactive PRL, it was possible to compare the bio- and immuno-potencies of hormone released from the same pituitary cells. The results of three separate studies revealed major differences among PRL secretors in these potency estimates. Given the existence of PRL variants with different biological and immunological efficacies, these findings suggest that PRL cells differ from one another in the molecular form(s) of hormone released. 
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: This article presents a protocol for the examination of the shoulder complex. The examination is divided into subjective and objective components. A primary focus of this article is on the functional portion of the objective examination and its interpretation. The functional examination consists of active and passive range-of-motion tests, accessory mobility tests, resisted tests, and palpation. This approach enables the examiner to classify movement disorders of the shoulder complex into dysfunctions of the noncontractile tissues and of the contractile tissues. Factors that enable the examiner to determine the severity of a pathological condition or to identify stages of the healing process are discussed. This information will assist the physical therapist in establishing treatment goals and in selecting appropriate strategies of therapeutic intervention.

SOLUTION: No

PROBLEM: Abstract: We report the causes of obstructive jaundice in 56 black South African patients. Chronic pancreatitis and malignant biliary obstruction occurred with equal frequency. These two conditions may be difficult to differentiate clinically and radiologically, and only operative pancreatic biopsy may be diagnostic. Choledocholithiasis caused jaundice in only 7.1% of the patients, reflecting the relatively low prevalence of gallstones in this population.
