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.

[EX Q]: Unintentional injuries are the leading cause of death in children, and falls are the most common type of unintentional injury in the US. The incidence of falls from windows, a common cause of death in urban areas, has not been described outside major cities such as New York and Chicago, and rates in urban and suburban areas have not been compared.', 'To estimate the incidence and identify the population at risk for falls from windows among children in Hamilton County, Ohio.', "Retrospective case series identified using Cincinnati Children's Hospital Medical Center (CHMC) Trauma Registry.", 'Hamilton County, Ohio, which has urban and nonurban areas.', 'Children less than 15 years old residing in Hamilton County, Ohio, presenting to CHMC in Cincinnati, Ohio, after a fall from a window between January 1, 1991, and December 31, 1997.', 'Annual incidence by age, race, gender, and residence of those who fell from windows.', 'Over the 7-year study period, 86 (6.3%) of 1,363 falls were from windows. The mortality rate for falls from windows was 4.7%, compared to 0.07% for all other falls presenting to CHMC (P<.0001). Children 0-4 years old had a higher rate of falls than children aged 5-14 (14.6/100,000 vs. 2.0/100,000) (P<.0001). Males were twice as likely to fall as females (P<.016), and black children were three times more likely to fall than non-black children (P<.002). The incidence of falls in the city of Cincinnati was four times that of the non-urban area (P<.0002).

[EX Q]: B-type natriuretic peptide (BNP) and N-terminal-pro-BNP (NT-pro-BNP) are important diagnostic tools for patients with suspected cardiac disorders. The aim of this study was to evaluate the predictive value of plasma NT-pro-BNP in identifying cardiac metastases in patients with non-small cell lung cancer (NSCLC) and dyspnoea.', 'A total of 120 patients, median age 62 years (range 46-83), with NSCLC and dyspnoea were studied. Patients with heart failure or documented coronary artery disease were excluded. Echocardiographic imaging was used to detect cardiac metastases and estimate global left ventricular function. Ejection fraction and E/A ratio from transmitral inflow pattern were calculated. Plasma NT-pro-BNP was also measured. 72 patients (72/120, 60%) with cardiac metastases were identified.', 'NT-pro-BNP was significantly higher in patients with metastases (1347.5 +/- 1004.30 pg/ml vs. 159.02 +/- 93.29 pg/ml; p = 0.001). No differences between groups, regarding s-creatinine (p = 0.45), haemoglobin (p = 0.71), left ventricular hypertrophy (p = 0.91), and diastolic dysfunction (p = 0.79), were observed.

[EX Q]: This study investigated the association between serum gamma-glutamyltransferase (GGT) level and subclinical atherosclerosis in patients with type 2 diabetes.', 'This cross-sectional study involved 1024 patients with type 2 diabetes mellitus. Measurement of brachial-ankle pulse wave velocity (baPWV; as a marker of arterial stiffness) and an ultrasound assessment of carotid atherosclerosis were performed. Subclinical atherosclerosis was defined by the presence of a high baPWV (≥1720\xa0cm/s), carotid atherosclerosis (intima-media thickness\xa0>0.8\xa0mm or the presence of plaques), and carotid stenosis (≥50\xa0% of luminal narrowing). The subjects were stratified into quartiles according to GGT level, and the relationship between GGT level and subclinical atherosclerosis was analysed.', 'Serum GGT levels were closely associated with obesity, atherogenic dyslipidemia, and metabolic syndrome. However, serum GGT levels did not show a linear association with baPWV, carotid intima-media thickness, or plaque grade. The prevalence of high baPWV, carotid atherosclerosis, and carotid stenosis did not differ between the quartiles in men and women. Multivariate logistic regression analyses revealed no association between GGT level and high baPWV, carotid atherosclerosis, and carotid stenosis, either as continuous variables or quartiles.
