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: Low-level activity at the end of the QRS complex was analyzed from 63 thoracic leads in 15 normal subjects and in 21 patients with ventricular tachycardia (VT). The latter had old myocardial infarction and no conduction disturbances and had not been receiving antiarrhythmic drugs. In both normal subjects and patients with VT, isopotential maps of the time-averaged and filtered (25 Hz high-pass) electrocardiograms during the terminal portion of the QRS were dipolar, i.e., they showed single positive and negative regions. For patients with VT, the extrema were either distant, with one over the precordial area and the other over the back, or close together in the precordial region. In 10 patients, maps recorded after administration of antiarrhythmic drugs remained the same while QRS duration was prolonged. In six patients, maps recorded before antiarrhythmic surgery showed distant extrema for septal or posterobasal VT sites of origin and close extrema for anterior or posteroapical sites. Generally, QRS duration was reduced and maps were modified after surgery. Late potentials can be well detected with only three orthogonal leads because their distributions are dipolar, but maps provide additional information about their distribution, which may be related to conduction delay sites and possibly to VT sites of origin. Sources near the torso surface would produce close extrema, whereas deeper sources would produce distant extrema.

Example Input: Abstract: During liquid preservation under blood bank conditions, red cell membranes inexorably undergo damage that decreases erythrocyte survival after transfusion. Accordingly, we have surveyed membrane skeletal protein interactions during storage. We uncovered a decrease in the in vitro formation of spectrin-actin complex in the absence (50%) or presence (60%) of protein 4.1. Actual formation of the spectrin-actin-protein 4.1 complex fell in a linear fashion during the storage period. This fall in spectrin-actin interaction tightly correlated with the decline in total red cell phospholipid (R = 0.9932) measured simultaneously. This decrement of spectrin-actin association could be restored to greater than 70% of normal values by preincubation of stored spectrin with 50 mM dithiothreitol. This storage injury to spectrin-actin interaction might weaken the membrane skeleton and lead to decreased red cell survival. In vitro reversibility of the damage by reducing agents suggests a possible new direction for prolonging the shelf life of stored blood.

Example Input: Abstract: To determine how various inheritance patterns and responses to splenectomy relate to erythrocyte spectrin deficiencies in hereditary spherocytosis, we measured the spectrin content of erythrocytes by radioimmunoassay in 33 patients with this disease. Patients with the dominant form of hereditary spherocytosis generally had mild anemia, with spectrin at 63 to 81 percent of normal levels. Patients with the nondominant form of the disease had anemia ranging from severe to mild, with corresponding spectrin levels of 30 to 74 percent; their siblings were affected similarly. Distantly related homozygotes had different clinical severities with correspondingly different spectrin levels. The parents and offspring of patients with the nondominant form were clinically normal but consistently had subtle erythrocyte abnormalities. Spectrin levels in all patients were inversely related to osmotic fragility (P less than 0.0001), and they were also correlated with the clinical response to splenectomy: patients with spectrin levels above 70 percent achieved normal blood counts, those with levels of 40 to 70 percent had compensated hemolysis, and those with levels below 40 percent improved but remained anemic (P less than 0.0001). We conclude that the inheritance pattern and response to splenectomy in hereditary spherocytosis reflect erythrocyte spectrin deficiencies as determined by radioimmunoassay.
