TASK 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.
PROBLEM: Abstract: Eosinophilic gastroenteritis most commonly involves the stomach and proximal small intestine with eosinophilic inflammation of either the mucosa, submucosa or serosa. The patient reported here had isolated eosinophilic colitis. The initial presentation with iron deficiency anaemia owing to occult gastrointestinal blood loss emphasises the need to evaluate the entire gastrointestinal tract in patients with eosinophilic gastroenteritis.
Question: Does the abstract contain any numerical data?

SOLUTION: No

PROBLEM: Abstract: A case of bilateral patella tendon rupture in an otherwise healthy 38-year-old man who sustained relatively minor trauma is presented. A flexion moment against a contracted or contracting quadriceps muscle is thought to have been the mechanism of injury. A survey of the literature yielded reports of three other cases of otherwise healthy patients who had had bilateral simultaneous disruption of the patella tendons.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: Previous studies of the effect of tricyclic antidepressants on left ventricular function in depressed patients with moderate to severe ventricular impairment have focused primarily on imipramine hydrochloride. In a prior study, we found that although imipramine had no effect on ejection fraction as measured by first-pass radionuclide angiography, the treatment could not be tolerated by 50% of the patients because of intolerable drug-induced orthostatic hypotension. Nortriptyline hydrochloride is an effective antidepressant that, in depressed patients without heart disease, causes significantly less orthostatic hypotension than imipramine. To see if this advantage could be safely extended to patients with congestive failure, we measured the effect of nortriptyline on ejection fraction and blood pressure in 21 depressed patients with left ventricular impairment. Ejection fraction was unchanged by nortriptyline treatment, and orthostatic hypotension developed in only one (5%) of 21 patients. Nortriptyline emerges as a relatively safe treatment for depression in patients with left ventricular impairment.
