Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.
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.
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: With the use of initial records of 1128 women who presented for interval tubal ligation, characteristics of those who were sterilized were juxtaposed with characteristics of those who did not return for surgery. Follow-up telephone interviews were conducted to explore regret after sterilization among 268 sterilized women. The subsequent histories of 144 women who did not return for surgery were examined, to determine whether failure to return might have screened, selectively, the women at greatest risk of regret. High levels of subsequent unwanted conception and pregnancy wastage were found in the nonreturn group. Institutional factors were often implicated in failure to return. Variables available at initial presentation are proposed to identify women who risk adverse consequences of postponed sterilization, to facilitate return without increasing regret.
Solution:
A study of women requesting interval contraceptive sterilization who do and do not return for surgery.
