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: 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?
Example output: Yes
Example explanation: As there are numerical figures and percentages (%), the answer is yes.
Q: Abstract: Primary leptomeningeal gliomas are rare. Historically, they have been found in the spinal canal more frequently; however, in the recent literature nearly all have been found within the cranium. In the only cadaveric study of leptomeningeal glial nests, the most frequent site was the medulla and pons. Until now, no leptomeningeal glioma has been found at this site. We report what we believe to be the first such case mimicking an acoustic neuroma. 
Question: Does the abstract contain any numerical data?

No
