Detailed Instructions: 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: 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.
Question: Does the abstract contain any numerical data?
Solution: Yes
Explanation: As there are numerical figures and percentages (%), the answer is yes.

Problem: Abstract: Pulsatile LH secretion was studied to determine if the frequency of LH pulses was altered by the administration of clomiphene citrate (CC; 150 mg) for 5 days during the midluteal phase of the menstrual cycle. Seven normal women received CC or placebo in alternate cycles in a randomized double blind fashion. On the day after drug administration, blood samples were obtained at 15-min intervals for 8 h for serum LH determinations. Daily blood samples were also obtained throughout the luteal phase for determination of serum LH, estradiol (E2), and progesterone. LH pulse frequency increased from 2.4 +/- 0.5 (+/- SEM)/8 h after placebo to 3.9 +/- 0.6/8 h (P less than 0.01) after CC treatment, but pulse amplitude did not change. The transverse mean of serum LH was higher after CC (13.6 +/- 0.5 mIU/ml) than after placebo (8.4 +/- 0.3 mIU/ml; P less than 0.001), and luteal phase length was increased from 13.5 +/- 0.5 to 16.0 +/- 0.4 days (P less than 0.001) by administration of CC. Luteal phase levels of E2 and progesterone measured daily were significantly elevated (P less than 0.01) in CC-treated cycles. These findings suggest that CC increases the frequency of hypothalamic GnRH secretory episodes, perhaps by an action involving a decrease in endogenous opioid peptide activity. Since peripheral progesterone levels were elevated in the CC-treated cycles, E2 may play a permissive role in the ability of progesterone to increase endogenous opioid peptide activity acutely. Furthermore, since the luteal phase was significantly prolonged by an increase in endogenous LH pulse frequency, the slow frequency of LH pulses in the normal late luteal phase may contribute to the onset of luteolysis in the human.
