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.

Ex Input:
Abstract: We treated a case of congenital membranous stenosis of the esophagus successfully by transendoscopic incision. We discuss various types of true congenital esophageal stenosis and their treatment, to distinguish these rare anomalies from the more frequently encountered acquired variety.

Abstract: Twenty one cases of amyloidosis of the lower respiratory tract were seen at a single center. In three patients, multifocal bronchial amyloid plaques led to stenosis and atelectasis, and in two, small pseudotumor masses were an incidental bronchoscopic finding. Two patients had nodular parenchymal amyloidosis, in one of whom the lesions were progressive and in the other static. Fifteen patients had diffuse parenchymal amyloidosis. Two of these had severe interstitial involvement and died in respiratory failure; eight had congestive cardiac failure, and parenchymal amyloidosis was a post-mortem finding; two had senile cardiorespiratory amyloidosis, also found at autopsy; and in three, the amyloidosis was associated with malignancy. The degree of respiratory embarrassment seemed to be related to the amount of amyloid in the gas diffusion zones, irrespective of the etiology of amyloidosis.

Abstract: This study evaluated train-of-four recovery after the administration of vecuronium, comparing measured with visually observed responses. Responses to supramaximal stimuli of the ulnar nerves were measured by a force transducer, and compared with visually observed movements of the contralateral thumb. For the 10 patients anaesthetized with nitrous oxide and enflurane, the second, third and fourth twitches visually reappeared at 84 (+/- 10)%, 76 (+/- 11)%, and 70 (+/- 12)% measured blockade, respectively. For the other 10 patients, anaesthetized with a narcotic-barbiturate technique, the second, third and fourth twitches reappeared at 81 (+/- 8)%, 68 (+/- 9)%, and 59 (+/- 11)%. These results were not different for the two anaesthetic techniques.
