Example Input: Abstract: We undertook a study of the separate and combined effects of age and sex on the pulsatile pattern of GH secretion. The 24-h secretory profile of GH was generated by 20-min sampling in 10 young women (aged 18-33 yr), 10 young men (aged 18-33 yr), 8 postmenopausal women (aged greater than 55 yr), and 8 older men (aged greater than 55 yr). A computer-assisted pulse analysis program was used to assess both total GH secretion, as reflected in the 24-h integrated GH concentration (IGHC), and pulsatile secretion, as denoted by pulse frequency, duration, amplitude, and the fraction of GH secreted in pulses during the 24-h period (FGHP). IGHC was significantly greater in women than in men (P less than 0.025) and greater in the young than in the old (P less than 0.003). The mean pulse amplitude, duration, and FGHP were each greater in the young (P less than 0.006, P less than 0.03, and P less than 0.0001, respectively), but not significantly different between the sexes. The mean pulse frequency was not affected by sex or age. The serum concentration of free estradiol, but not free testosterone, correlated with IGHC (r = 0.46; P less than 0.005), pulse amplitude (r = 0.53; P less than 0.001), and FGHP (r = 0.59; P less than 0.0002). After correcting for the effects of estradiol, neither sex nor age influenced IGHC or mean pulse amplitude, while the effect of age on FGHP was reduced from 81% to 29%. Of the indices of GH secretion, FGHP had the strongest correlation (r = 0.43; P less than 0.006) with somatomedin-C. Somatomedin-C declined significantly with age in both sexes. Our results indicate that sex and age have independent and interrelated effects on GH secretion. These effects can be largely accounted for by corresponding variations in endogenous estradiol levels. These observations suggest an amplifying action of estradiol on the neuroendocrine regulation of pulsatile GH release. 
 Which is the apt title for the abstract? option1: Effects of sex and age on the 24-hour profile of growth hormone secretion in man: importance of endogenous estradiol concentrations. option2: Thalidomide neuropathy: an electrophysiologic study.
Example Output: Effects of sex and age on the 24-hour profile of growth hormone secretion in man: importance of endogenous estradiol concentrations.

Example Input: Abstract: To study patient preferences on physician attire and etiquette, we interviewed 200 patients on the general medical services of teaching hospitals in Boston and San Francisco. Of these 200 patients, 65% believed physicians should wear a white coat, 27% believed physicians should not wear tennis shoes, 52% believed physicians should not wear blue jeans, 37% believed male physicians should wear neckties, and 34% believed female physicians should wear dresses or skirts. Forty percent of patients wanted physicians to address them by first name, but only 10% of patients wanted to address their physicians by first name. A concurrent mailed survey of 74 medical house staff members at the two hospitals revealed wide variability in physicians' attire and in how patients were addressed at each institution. Thus, many house officers had habits that were less formal than a substantial portion of their patients preferred.

Example Output: Patient and house officer attitudes on physician attire and etiquette.

Example Input: Abstract: A retrospective review was conducted to assess the effect of molindone on weight. Monthly weights and neuroleptic dosages during the first three months of psychiatric hospitalization were compared between matched groups of patients receiving molindone, a combination of molindone and other neuroleptics, or other neuroleptic drugs. We found no significant differences in weight gain among the three groups. Our results challenge the common opinion that molindone can be associated with a lack of weight gain compared to other antipsychotics. 
 Which is the apt title for the abstract? option1: Effect of molindone on weight change in hospitalized schizophrenic patients. option2: Progress in inflammatory breast cancer: cause for cautious optimism [editorial]
Example Output:
