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).
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.
Example solution: Refibrillation managed by EMT-Ds
Example 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.

Problem: Abstract: The serum testosterone level (STL) was determined in 84 male and 32 female patients with gastric carcinoma and in 58 male and 20 female patients with benign diseases as a control group. The STL of the male patients with carcinoma was lower (446 +/- 149 ng/dl) than that of the male control group (532 +/- 132 ng/dl) (P less than 0.001). Even 17 male patients of the early carcinoma showed lower STL (440 +/- 117 ng/dl) than the normal group (P less than 0.001). In the female patients, it was also lower (31.6 +/- 16.0 ng/dl) than in the control group (46.3 +/- 15.3 ng/dl) (P less than 0.005). The postoperative STL of the cases surviving the gastrectomy was higher than the preoperative data in 32 male patients (P less than 0.005) as well as in 12 female patients (0.025 greater than P greater than 0.01), whereas it obviously decreased in the patients who died of recurrence. Therefore, it appears that gastric carcinoma decreases the STL by some mechanism. 
 Which is the apt title for the abstract? option1: Serum testosterone level of patients with gastric carcinoma before and after gastrectomy. option2: Wheelchair use by ambulatory nursing home residents.

Solution: Serum testosterone level of patients with gastric carcinoma before and after gastrectomy.
