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.

Let me give you an 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?
The answer to this example can be: Yes
Here is why: As there are numerical figures and percentages (%), the answer is yes.

OK. solve this:
Abstract: In male Wistar rats, renal adenosine triphosphate (ATP), inorganic phosphate (Pi) and intracellular pH were measured by 31phosphorus nuclear magnetic resonance (31P NMR) and correlated with renal function before, during, and for one hour after a period of 30 to 40 minutes hemorrhagic hypotension. In animals which suffered no change in these metabolites during hypotension, retransfusion immediately restored normal renal function. When metabolite changes were observed during hypotension, they occurred suddenly with severe ATP depletion, Pi accumulation, and intracellular acidosis occurring almost concurrently. Metabolic changes of this magnitude were always associated with renal dysfunction in the post-hypotensive period, which occurred even when the period of biochemical change was only 10 to 15 minutes. The abnormalities in post-hypotensive renal function resemble the pattern of change seen in human acute tubular necrosis (ATN): depressed glomerular filtration rate (GFR), urine output varying from polyuria to oliguria, decreased urine to plasma inulin ratio, increased urinary sodium concentration, increased fractional excretion of sodium, and increased fractional excretion of potassium. It is postulated that changes in renal cellular energy status during hemorrhagic hypotension distinguish pre-renal failure from early or incipient ATN.
