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: 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?
Solution is here: Yes
Explanation: As there are numerical figures and percentages (%), the answer is yes.

Now, solve this: Abstract: The ability of insulin to stimulate tissue glucose uptake and lower plasma FFA concentrations was quantified in 12 individuals with normal glucose tolerance and 12 patients with noninsulin-dependent diabetes mellitus (NIDDM), further subdivided into obese and nonobese subjects. Measurements were made during 5-h glucose clamp studies, carried out at plasma insulin concentrations of about 10 microU/ml (0-150 min) and about 60 microU/ml (150-300 min). Differences between the patient groups were compared by two-way analysis of variance. The ability of insulin to either suppress plasma FFA concentrations or stimulate glucose uptake was significantly reduced (P less than 0.001) in patients with NIDDM, and this was true of both the obese and nonobese groups. The defect in the ability of insulin to suppress plasma FFA concentrations in patients with NIDDM was more apparent at the lower insulin concentration, whereas resistance to insulin-stimulated glucose uptake in NIDDM was more dramatic at the high insulin concentration. Finally, a significant correlation (r = -0.67; P less than 0.001) between insulin-stimulated glucose uptake and plasma FFA concentration was found in the entire group. These data emphasize the fact that patients with NIDDM are resistant to multiple actions of insulin, and that the magnitudes of the defect in insulin suppression of plasma FFA levels and stimulation of tissue glucose uptake are roughly comparable.
