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.
One example is below.
Q: 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?
A: Yes
Rationale: As there are numerical figures and percentages (%), the answer is yes.
Q: Abstract: A series of 150 patients with histologically confirmed angiofibroma examined from 1945 through 1983 was studied to contrast treatment methods and surgical approaches. From 1945 to 1955, treatment consisted primarily of radiation. From 1955 through 1971, the primary method of treatment was surgical removal; the lateral rhinotomy approach was used to expose the tumor and its extensions in most cases. From 1971 through 1983, all tumors were removed surgically. Trends in diagnosis, treatment, and adjunctive therapy at a single institution were evaluated. Specifically, the trends considered were operative approaches, blood replacement with and without hypotensive anesthesia, adjunctive measures such as hormonal therapy or tumor embolization, mortality, and morbidity. Lateral rhinotomy provides wide exposure of and access to the nose, nasopharynx, paranasal sinuses, elements of the skull base, temporal fossa, and infratemporal fossa. Surgical treatment, specifically the lateral rhinotomy approach and its extensions, is recommended as the best method of managing angiofibroma in most patients.
