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: The acquired immune deficiency syndrome has presented a complex and, as yet, unsolvable spectrum of pulmonary disease characterized by bizarre infections, pneumothoraces, respiratory distress, and death. Thirty-eight patients underwent 49 surgical procedures during 42 months. Ages of the patients ranged from 24 to 56 years. Surgical procedures included tracheostomy, closure of air leaks, mediastinoscopy, lobectomy, open lung biopsy, and esophagogastrectomy. Hospital mortality was 10 of 38 (24%); the 1 year survival rate was 13 of 38 (34%). Pulmonary infections included Pneumocystis carinii, cytomegalovirus, Microbacterium avium, toxoplasmosis, candidiasis, and Cryptococcus neoformans. Open lung biopsy and surgical closure of air leaks can be accomplished safely with low morbidity. Tracheostomy and ventilatory support should be avoided at present in the majority of patients with this syndrome, as the mortality has been 100% when that stage of the disease is reached.
