Detailed Instructions: 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.
See one example below:
Problem: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation - trained ambulance technicians(EMT - Ds) will refibrillate before hospital arrival.The authors analyzed 271 cases of ventricular fibrillation managed by EMT - Ds working without paramedic back - up.Of 111 patients initially converted to organized rhythms, 19(17%) refibrillated, 11(58%) of whom were reconverted to perfusing rhythms, including nine of 11(82%) who had spontaneous pulses prior to refibrillation.Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53 % versus 76% , P = NS), although discharge rates were virtually identical(37 % and 35 % , respectively).Scene - to - hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome.Defibrillation - trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back - up is not available.
Question: Does the abstract contain any numerical data?
Solution: Yes
Explanation: As there are numerical figures and percentages (%), the answer is yes.

Problem: Abstract: Of 34 tibia fractures in 28 acute spinal cord injuries, 13 patients had complete and 15 had incomplete neurologic lesions. Tibia fractures were divided into three groups: Group I, nonoperative treatment; Group II, early open reduction and internal fixation; and Group III, Type III open injuries. Group I included 17 fractures, of which nine (53%) had delayed union, malunion, or nonunion. The average time to union was 6.5 months. Seven patients had pressure sores and pulmonary emboli. Eleven fractures were noted in Group II. One delayed union (9%), one superficial wound infection that healed uneventfully, and one deep vein thrombosis were noted. The average time to union was 12 weeks. All six Group III tibias had delayed and nonunions, regardless of treatment. Nonoperative fractures healed at a prolonged rate, while open reduction and internal fixation enhanced the rate and time to union. Fractures treated with early open reduction and internal fixation, excluding Group III patients, had the least orthopedic and medical complications. Open reduction and internal fixation is a justifiable alternative to nonoperative treatment in the uncomplicated tibia fracture regardless of neurologic lesion for improved medical and fracture care.
