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? Solve this instance: Abstract: Foreign body aspiration in children is frequently associated with unilateral emphysema or atelectasis on chest x-ray. Two cases are reported of tracheal or bilateral foreign bodies in which the original chest x-rays were read as normal, but the history was suggestive of the foreign body aspiration. Early bronchoscopy can prevent the long-term morbidity that results from unrecognized tracheobronchial foreign bodies.
Question: Does the abstract contain any numerical data?

No
