You will be given a definition of a task first, then some input of the task.
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.

Abstract: Stress fracture of the fourth vertebral arch occurred in a 21-year-old woman with a benign osteopetrosis. The fracture healed in three months after application of a body cast. It seems likely that the osteopetrotic bone resists force, in parallel with the cortical layer, but is fragile to forces at right angles to the plane of the cortical layer.
Question: Does the abstract contain any numerical data?
Output:
Yes
