Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
One example: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
Which is the apt title for the abstract? option1: Refibrillation managed by EMT-Ds option2: Maintenance of compliance in a small diameter arterial prosthesis.
Solution is here: Refibrillation managed by EMT-Ds
Explanation: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.

Now, solve this: Abstract: Ninety patients were studied in a controlled, randomized fashion to evaluate the effectiveness of topical 5-fluorouracil in reducing the recurrence rate of human papillomavirus-associated lesions of the vulva and vagina. Following complete ablation of the lesions by one or more treatment modalities, 45 patients applied a single dose of 5% 5-fluorouracil cream biweekly to the vagina and/or vulva for at least six months. Forty-five patients used no prophylactic 5-fluorouracil cream. Patients in both groups were comparable with regard to race, age, and immune status, as well as the number, location, duration, clinical appearance, histology, and prior treatment of the lesions. Six patients (13%) with 5-fluorouracil prophylaxis and 17 (38%) without additional treatment (P less than .01) developed recurrent lesions during a follow-up time of nine to 22 months (mean = 14.4 months). Maintenance therapy with 5-fluorouracil was most effective in women with multiple lesions, multiple organ involvement, or with a depressed immune system.
Which is the apt title for the abstract? option1: Prophylactic topical 5-fluorouracil following treatment of human papillomavirus-associated lesions of the vulva and vagina. option2: Radiographic vs. direct measurements of the spinal canal of the thoracolumbar junctional region (T10-L1) of the spine.
Solution:
Prophylactic topical 5-fluorouracil following treatment of human papillomavirus-associated lesions of the vulva and vagina.
