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: In six spontaneously breathing anesthetized dogs (pentobarbital sodium, 30 mg/kg) airflow, volume, and tracheal and esophageal pressures were measured. The active and passive mechanical properties of the total respiratory system, lung, and chest wall were calculated. The average passive values of respiratory system, lung, and chest wall elastances amounted to, respectively, 50.1, 32.3, and 17.7 cmH2O X l-1. Resistive pressure-vs.-flow relationships for the relaxed respiratory system, lung, and chest wall were also determined; a linear relationship was found for the former (the total passive intrinsic resistance averaged 4.1 cmH2O X l-1 X s), whereas power functions best described the others: the pulmonary pressure-flow relationship exhibited an upward concavity, which for the chest wall presented an upward convexity. The average active elastance and resistance of the respiratory system were, respectively, 64.0 cmH2O X l-1 and 5.4 cmH2O X l-1 X s. The greater active impedance reflects pressure losses due to force-length and force-velocity properties of the inspiratory muscles and those due to distortion of the respiratory system from its relaxed configuration.
Question: Does the abstract contain any numerical data?
Example Output: Yes

Example Input: Abstract: An accurate diagnosis is essential in managing musculoskeletal problems in children. Active treatment is only occasionally necessary and should meet the criteria of being essential, effective, and prudent.

Example Input: Abstract: From 1977 through 1984, 58 arterial reconstructions using glutaraldehyde-tanned human umbilical vein (H.U.V.) grafts were carried out: 41 femoropopliteal, 4 composite aortopopliteal (a Dacron graft was inserted proximally), 5 femorotibial, 6 axillofemoral, 1 femorofemoral, and 1 iliofemoral bypass. Autogenous saphenous vein was absent or inadequate in all patients. Limb salvage was the primary indication for surgery (89.7%). Five and 8 years cumulative patency rates were 42.8% and 35.1% respectively for all H.U.V. by-passes and 52.4% and 41.9% respectively for femoropopliteal by-passes. Four out of the 5 femorotibial by-passes failed during the first month following surgery. Two of the 6 axillofemoral and 3 of the 4 composite aortopopliteal by-passes thrombosed within 1 and 3 years after surgery, respectively. Perioperative mortality was 5.1%, while overall mortality was 17.2%. The following conclusions can be drawn from these results: H.U.V. grafts did not achieve cumulative patency rates superior to those reported with autogenous saphenous vein, in limb salvage situations, when the saphenous vein is not available, the H.U.V. graft offers acceptable salvage rates, results from the 8-year follow-up period demonstrate the durability and long-term patency of H.U.V. grafts.
