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.

Let me give you an example: 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?
The answer to this example can be: Yes
Here is why: As there are numerical figures and percentages (%), the answer is yes.

OK. solve this:
Abstract: Chondrosarcoma of the temporal bone is a rare lesion. Clinically it has been confused with multiple sclerosis, glomus jugulare tumors, meningioma, and chordomas. The cranial nerve palsies frequently observed with the tumors are related to the anatomic locations of the tumors. Thirteen patients with this entity are presented and the eleven other cases in the literature are reviewed. Histologically the tumors are low grade and exhibit myxoid features. The myxoid features must be differentiated from chordoma and chondroid chordoma. The tumor locations preclude surgical excision and conventional radiation therapy can cause unacceptable neurologic sequelae. Proton beam therapy has been effective in short-term results and appears capable of avoiding serious neurologic side effects.
