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.
Input: Abstract: During infragenicular bypass, internal occlusion of the distal vessel avoids unnecessary dissection and potentially damaging use of external clamps or vessel loops while improving exposure and patency. This technique is especially useful in patients with small or calcific vessels in whom distal reconstruction is necessary for limb salvage.
Question: Does the abstract contain any numerical data?
Output:
No
