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: Dermatitis from 2-chloromethyl-4-phenyl-6-chloroquinazoline-3-oxide, an intermediate product in the preparation of chlorodiazepoxide, is described in 29 workers at a pharmaceutical plant. All were patch test positive to quinazoline oxide (1%) and six to 0.05%. In most patients, the face was earlier and more severely involved than the hands. Some were sensitized even if they did not have much contact with it, doing such work as washing the clothing of other workers, or working at a distance of 100 m from the production line building.

Abstract: We studied the importance of a history of appendectomy for appendicitis in 279 women with laparoscopically or surgically diagnosed tubal infertility and a control group of 957 fertile women. After controlling for the effects of age, use of an intrauterine device for contraception, a history of pelvic inflammatory disease, and other potential confounding variables, we found that no excess risk of tubal infertility was associated with a simple appendectomy without rupture. However, when the operation was reportedly for a ruptured appendix, the relative risk of tubal infertility was 4.8 (95 percent confidence interval, 1.5 to 14.9) for women who had never been pregnant and 3.2 (95 percent confidence interval, 1.1 to 9.6) for women with one or more previous pregnancies. We conclude that the early diagnosis and treatment of suspected appendicitis in girls and women of reproductive age may reduce the incidence of tubal infertility resulting from the sequelae of a ruptured appendix.

Abstract: A newborn with paraplegia and evidence of a subarachnoid hemorrhage was found to have a spinal arteriovenous malformation. The arteriovenous malformation was managed by direct surgical obliteration. This patient is the youngest ever reported to have this disorder and the youngest so treated.
