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: Electrocardiographic monitoring and provocative ventricular pacing were used to evaluate control and nadolol treatment groups 6 to 24 hours after left anterior descending coronary artery ligation in the dog. During the 6 to 24 hour period, the control group (n = 20) developed ventricular triplets at rates exceeding 270/min. Seven dogs spontaneously developed sustained monomorphic ventricular tachycardia (421 +/- 12 beats/min) at 13 +/- 2 hours. Sustained monomorphic ventricular tachycardia was present for 38 +/- 8 seconds before ventricular fibrillation developed. One dog developed recurrent monomorphic ventricular tachycardia, with six episodes lasting from 8 to 72 seconds (375 to 425 beats/min). At 24 hours, ventricular pacing produced sustained monomorphic ventricular tachycardia (378 +/- 12 beats/min) in 9 of 13 surviving animals. Nadolol administration 6 hours after coronary artery ligation (n = 19) lowered both the rate (241 +/- 8 versus 328 +/- 8 beats/min; p = 0.001) and the incidence (8 +/- 6 versus 198 +/- 61 per hour; p = 0.004) of rapid ventricular triplets and prevented sudden arrhythmic death (0%; p = 0.005). Nadolol failed to prevent sustained monomorphic ventricular tachycardia (88%; 365 +/- 12 beats/min) produced by ventricular pacing. The data suggest that nadolol prevents spontaneous sustained monomorphic ventricular tachycardia by selectively suppressing the arrhythmia trigger (rapid ventricular triplets) without altering the underlying arrhythmia substrate.
