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: Ewes were treated systemically during the periovulatory period with the antihistamines diphenhydramine (H1-receptor antagonist) and(or) cimetidine (H2-receptor antagonist). None of the treatments prevented ovulation. However, the combination of drugs inhibited subsequent function of the corpus luteum (CL) as assessed by serum measurements of progesterone. Administration of antihistamines did not alter pituitary secretion of LH. Injection of small quantities of diphenhydramine and cimetidine into the antrum of the preovulatory follicle also caused aberrant luteal activity, but no blockade of ovulation. Intrafollicular injection of histamine reversed the inhibitory influence of antihistamines on the CL. Antihistamines suppressed preovulatory thecal edema and antral influx of plasma transudate containing LH. Thus, the effects of antihistamines appear to have been exerted at the follicular level. Function of matured CL was not compromised by peripheral administration of antihistamines. Actions of histamine within the preovulatory ovine follicle do not appear to be a prerequisite for ovulation, but apparently do have an impact on ensuing luteal function. We propose that a hyperemic reaction to histamine in preovulatory follicles enhances vascular filtration of LH. As a consequence, maximal permeation of the avascular granulosal layer of the follicle by LH leads to a normal luteinization response.
