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: In earlier studies, it was shown that the human plasma-spreading glycoprotein, epibolin (the 65 kD species of serum-spreading factor or vitronectin), requires a second plasma component, termed coepibolin, in order to support maximal dissociated epidermal cell spreading in tissue culture. Whereas epibolin alone in defined medium supports some cell spreading, the purified plasma coepibolin preparations do not effect spreading in the absence of epibolin. Although not yet entirely purified, coepibolin associates with some plasma fractions but not with others; it is certainly not a property of all proteins, e.g., while bovine serum albumin (BSA) has coepibolin activity, ovalbumin does not. The data presented here show that the phorbol ester, 12-tetra-decanoyl-1-phorbol-13-acetate (TPA) can act as a potent coepibolin and support maximal spreading over a concentration range of 10-100 ng/ml. In the absence of epibolin TPA does not stimulate the spreading of epidermal cells when given alone or in the presence of BSA or ovalbumin. Coepibolin activity appears to associate with tumor-promoting activity in that the phorbol derivative, phorbol-12,13-didecanoate, shows coepibolin activity, while its inactive non-tumor-promoting isomer, phorbol-4 alpha-phorbol-12,13-didecanoate, does not. These data suggest that the proteinaceous plasma-derived cofactor acts in a fashion similar to TPA and that this as yet unexplained mechanism of TPA action is important to the full expression of epibolin and to the early phase of epidermal cell spreading.
