Part 1. Definition
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.
Part 2. 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?
Answer: Yes
Explanation: As there are numerical figures and percentages (%), the answer is yes.
Part 3. Exercise
Abstract: Symptomatic assessment and oesophageal investigations were done in 25 consecutive patients with the irritable bowel syndrome attending a gastroenterological clinic. Symptoms of gastro-oesophageal reflux, dysphagia, and a globus sensation were significantly commoner than in a control group of fracture clinic patients. Ambulatory oesophageal pH monitoring showed clearly abnormal reflux in 11 of 22 patients (50%). Nine patients had macroscopic endoscopic changes and a further 11 biopsy changes alone, of oesophagitis which was thus present in 80% overall. Lower oesophageal sphincter pressure was significantly less in irritable bowel patients than in age and sex matched controls, but upper oesophageal sphincter pressure was comparable in the two groups and disordered peristalsis was not found. Oesophageal symptoms in the irritable bowel syndrome are mainly caused by gastro-oesophageal reflux predisposed to by a subnormal lower oesophageal sphincter pressure, rather than by oesophageal spasm.
