TASK 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.
PROBLEM: Abstract: Faecal metronidazole and hydroxymetronidazole concentrations measured by high pressure liquid chromatography are reported during 10 episodes of Clostridium difficile colitis in nine patients. Bactericidal faecal concentrations were present in all patients with acute disease receiving oral or intravenous metronidazole, and all responded to therapy. Metronidazole and hydroxymetronidazole concentrations fell as the diarrhoea improved and neither substance was detectable in the faeces of five patients after recovery. This demonstration of intracolonic therapeutic concentrations of metronidazole supports the clinical experience of oral metronidazole being effective in the treatment of antibiotic associated diarrhoea caused by C difficile and also suggests a potential role for intravenous metronidazole in this disease.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: Cannulation of the fimbriated end of the fallopian tube during gamete intrafallopian tube transfer (GIFT) may be at times extremely difficult and even require minilaparotomy. An ideal laparoscopic GIFT catheter should be flexible and stirrable, have a small diameter, and yet be sturdy enough to enable its manipulation. Such a catheter was developed in collaboration with Cook Ob/Gyne, a Division of Cook Inc., Indiana, with primary emphasis on easy laparoscopic manipulation. Its use in eight attempts of GIFT resulted in three pregnancies (37%).

PROBLEM: Abstract: A general approach to the child with foot pain has been described. In that the pediatrician is so often the recipient of parent's questions about children's shoes, he or she should be aware of problems relating to poorly fitting shoes, probably the most common source of complaints of foot pain in children. With a systematic approach, the pediatrician is very capable of managing the majority of such complaints.
