Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Context: To compare the frequency of Pap test results in a prospective series of direct to vial ThinPrep tests to a cohort of conventionally prepared tests. To follow-up all test results for a minimum of 2 years and assess performance based on this outcome.', 'All women presenting for either routine screening or colposcopic examination in 2001 were enrolled in the ThinPrep cohort. A similar, population of conventionally prepared tests was extracted from the year 2000 laboratory data. Information on all concurrent and follow-up cervical specimens over the ensuing 2 years was retrieved.', 'The ThinPrep cohort comprised 2288 Pap tests and the conventional, 2211. The frequency of normal [within normal limits (WNL) and benign cellular changes (BCC)] results in the ThinPrep cohort was 6% lower and the frequency of abnormal [> or =atypical squamous cells of undetermined significance (ASCUS)] results was 6.8% higher. Respective ThinPrep and conventional cohort results were 1156 (51%) and 1291 (58%) WNL, 625 (27%) and 561 (25%) BCC, 101 (4%) and 65 (3%) ASCUS, 21 (1%) and 2 (0.1%) atypical glandular cells of undetermined significance, 301 (13%) and 224 (10%) low-grade squamous intraepithelial lesion (LSIL), and 74 (3%) and 40 (2%) high-grade SIL (HSIL) (P < 0.0001). Follow-up was available for nearly 80% of each cohort. LSIL or higher was confirmed in 57.5% (n = 266) of the abnormal ThinPrep and 60.9% (n = 190) of the abnormal conventional tests. The ThinPrep yield of confirmed tests however was almost 50% higher than the conventional test.
Answer: In this population, ThinPrep was superior to the conventional Pap test.

Output: Does comparative study of the ThinPrep Pap test and conventional cytology result in a Canadian cohort?


Input: Consider Input: Context: MicroRNAs play important roles in regulation of the initiation and progression of AML. MiR-210 is closely related with cancer development; however, whether miR-210 expression level correlates with clinical correlation in AML is unknown. Thus, the aim of this study was to investigate the potential relationship between miR-210 expression and AML prognosis.', 'Real-time quantitative PCR was carried out to examine the expression level of miR-210 in bone marrow and serum obtained from AML patients and healthy controls. Then the correlation between miR-210 expression and a variety of important clinical parameters (such as overall survival, relapse-free survival, and prognostic value) were further studied.', 'The expression level of miR-210 was significantly higher in the bone marrow and serum of AML patients than that of healthy controls (p<0.001). Moreover, miR-210 expression was associated with various AML clinicopathological parameters, including FAB classification and cytogenetics. The serum miR-210 expression level was reduced significantly when the patients achieved complete remission (p=0.02). The high miR-210 expression group had both poorer relapse-free survival (p=0.015) and worse overall survival (p=0.008). In the multivariate analysis model, miR-210 was identified as an independent prognostic marker.
Answer: MiR-210 up-regulation was associated with poor prognosis in AML and it might be useful as a marker for predicting the clinical outcome of AML patients.

Output: Is overexpression of miR-210 Associated with Poor Prognosis of Acute Myeloid Leukemia?


Input: Consider Input: Context: In children there is frequently a reason to exclude cystic fibrosis. Sweat testing is used for this. Because sweat testing has some disadvantages we investigated whether analyzing DNA for the local most common CFTR mutations, harvested from buccal cells, is reliable as a method to exclude cystic fibrosis.', 'In patients in whom a sweat test had been ordered during the period January 1, 2002 to December 31, 2004, we harvested buccal cell DNA for analysis. When blood was available, DNA from leukocytes was also analyzed.', 'A total of 73 sweat tests were ordered during the two-year study period, mostly because of recurrent pulmonary infections (36; 49%), failure to thrive (20; 27%) and chronic diarrhea (10, 14%). In 70, children the results of the sweat test were normal, in three patients the results were borderline. Sixty buccal smears were analyzed and no patient was homozygous for cystic fibrosis, two were heterozygous for cystic fibrosis. In none of the children the diagnosis of cystic fibrosis was established.
Answer: Analyzing DNA in cells, harvested from the buccal cells, is a reliable alternative to exclude cystic fibrosis. It is safe, simple, and child-friendly.


Output: Is analyzing DNA from buccal cells a reliable method for the exclusion of cystic fibrosis . Results of a pilot study?
