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: We have developed a new cellulose membrane in which the active hydroxyl and carboxyl groups of the original cellulose fibers are masked with cationic synthetic polymers. The membrane was shown by in vitro and clinical tests to affect the activation of the complement system very little, and it retains the high dialysis efficiency, good tolerance to steam autoclave sterilization, and economical production cost characteristics of the original cellulose membrane. It thus appears that the new cellulose provides the optimum combination of qualities needed in a hemodialysis membrane.
Question: Does the abstract contain any numerical data?

SOLUTION: No

PROBLEM: Abstract: Serum cord total bilirubin levels can define a subgroup of infants who are at a higher risk for developing significant hyperbilirubinemia and requiring phototherapy. Infants with cord bilirubin levels less than 2.0 mg/dL have only a 4 percent chance of developing hyperbilirubinemia and a 1.4 percent chance of needing phototherapy. However, if serum cord bilirubin levels are more than 2.0 mg/dL, the infant has a 25 percent chance of developing subsequent hyperbilirubinemia. With early discharge from the nursery a more common practice, this level can identify at an early age those infants who need closer follow-up.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: Norepinephrine concentrations and tyrosine hydroxylase activity were determined in the brains of moderate-seizure and severe-seizure genetically epilepsy-prone rats (GEPRs) and in nonepileptic control rats. Both moderate-seizure (GEPR-3) and severe-seizure (GEPR-9) animals had widespread abnormalities in brain norepinephrine concentrations. Abnormalities in tyrosine hydroxylase activity were restricted to the midbrain. The state of abnormal seizure susceptibility, but not severity, in the GEPR may be determined by noradrenergic deficits in the hypothalamus/thalamus. Both seizure severity and susceptibility may be determined by noradrenergic deficits in the telencephalon, midbrain, and pons-medulla. Seizure severity but not susceptibility may be determined by noradrenergic abnormalities in the cerebellum.
