Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: Yes
Reason: As there are numerical figures and percentages (%), the answer is yes.

Now, solve this instance: Abstract: This report describes the occurrence of immune complex glomerulonephritis in a patient with eosinophilic gastroenteritis and food hypersensitivity. A coincident allergen injection may have been a contributing factor in the sudden development of the nephrotic syndrome. Markedly elevated levels of circulating immune complexes (greater than 6400 mg/dl) were found containing kappa-casein and bovine serum albumin (BSA), the latter predominating. Markedly elevated serum BSA hemagglutinating titers were also present (1:40,960). Cross-reacting precipitating antibodies to BSA, beef, and pork were demonstrated, but not to flounder or ovalbumin. Renal biopsy revealed immune complex glomerulonephritis with BSA, immunoglobulins M and G and complement deposited focally in the glomerular basement membrane. With strict dietary limitation of identified causative antigens and prednisone therapy, CIC levels decreased to 16,000 micrograms/dl and serum BSA antibody hemagglutinating titer fell 32-fold over a period of 15 months. There was prompt symptomatic relief and amelioration of signs of nephritis. The patient was able to consume a diet normal in protein and caloric content, and statural catch-up growth occurred. Recognition of food antigens to which the patient was hypersensitive provided a rationale for the relief of the gastrointestinal disturbance, growth stunting, and renal disease.
