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: A 56-year-old woman presented with a 10-year history of torsional diplopia and right monocular oscillopsia. These symptoms, which had been intermittent at first, continued practically uninterrupted during the last 2 years. She was diagnosed as having superior oblique myokymia of the right eye. Adequate trials of oral carbamazepine, baclofen and phenytoin were unsuccessful in suppressing her symptoms. One year after her initial presentation, she underwent a right superior oblique tenectomy and a right inferior oblique recession. She eventually required a second operation on her other eye to cure her of an annoying diplopia on down-gaze.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: Four patients who had no oocytes retrieved during an IVF cycle were studied in an attempt to identify predictors of such an occurrence and suggestions for its cause. All 30 follicles aspirated in five cycles in these four women yielded no oocytes. One patient had two cycles that produced no eggs. The empty follicle syndrome may represent a new syndrome and a cause of infertility.

PROBLEM: Abstract: Guiding surgical therapy of ventricular tachycardia by preoperative endocardial catheter mapping necessitates improvement of the accuracy of localization of the arrhythmogenic site. We therefore used a new mathematical cineradiographic method during catheter mapping to compute the position of left ventricular arrhythmogenic sites relative to three anatomic reference points: the centers of aortic and mitral valve ostia and the left ventricular apex. To enable the surgeon to identify the position of the computed sites, a wire skeleton (one for each patient) representing a single or multiple arrhythmogenic site(s) relative to the anatomic reference points was constructed. This wire skeleton was inserted into the left ventricular cavity during surgery. Side branches of the device indicated preoperatively localized arrhythmogenic sites. Results in eight consecutive patients were compared with those of intraoperative simultaneous mapping of 64 endocardial sites. Sixteen morphologically distinct monomorphic ventricular tachycardias were mapped by catheter and 15 by intraoperative mapping. In 12 ventricular tachycardias an identical morphology was recorded during both techniques. The distance between arrhythmogenic sites localized with both methods was 1 cm or less in 11 of these 12 ventricular tachycardias and 2 cm in one ventricular tachycardia. These results indicate that endocardial catheter mapping combined with wire skeleton representation of computed positions of arrhythmogenic sites is reliable for guiding surgical therapy of ventricular tachycardia and since some of the ventricular tachycardias were inducible only during either preoperative or intraoperative mapping, both techniques have an additive value. In addition, the wire skeleton proved convenient during surgery by identifying the arrhythmogenic sites.
