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: Two hundred and seventy-seven patients with advanced prostatic cancer were treated by either orchiectomy or oestrogen. During the 2-year follow-up period, the response to treatment was considered more favourable in the oestrogen group, and this response was particularly emphasised in patients with poorly differentiated tumour and metastases at the time of diagnosis. Further evaluations included the cardiovascular side effects of oestrogen therapy.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: Patients with essential hypernatremia maintain urinary concentrating ability despite plasma hyperosmolality and low plasma vasopressin concentrations. We investigated renal sensitivity to ultralow dose vasopressin infusions in two patients with a syndrome of hypodipsia, hypernatremia with selective osmoreceptor dysfunction, early puberty, and aggressive behavior. The patients were water loaded until a hypotonic diuresis was established. Vasopressin was infused in stepwise increments from 0.4-12 fmol/kg X min. Both patients had increased renal sensitivity to vasopressin, achieving negative free water clearance at infusion rates of 0.4 and 4 fmol/kg X min (normal greater than or equal to 6). Treatment for 3 months with 1-desamino-8-D-arginine vasopressin (DDAVP) led to an improvement in behavior and the reporting, for the first time, of a sensation of thirst. After DDAVP therapy both patients had a reduction of their renal sensitivity to infused vasopressin. We conclude that untreated patients with essential hypernatremia have increased renal sensitivity to vasopressin which is reduced by DDAVP administration.

PROBLEM: Abstract: Eighty-two women with symmetric cornual blockage were selected for evaluation of the results of microsurgical anastomosis in relation to data from preoperative hysterosalpingography and histologic study of excised tubal specimens. Serial sections from 164 occluded tubal portions were examined. The term pregnancy rate was 44%. Several prognostic factors influencing the postoperative pregnancy rate were revealed: maximized tubal length; preserved intramural portion; absence of chronic inflammation; absence of tubal inclusion in the tubal wall; and absence of tubal endometriosis.
