Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. 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.

Context: Almost all the past CSWT studies show the beneficial effects on CAD patients in a maximum duration of 1-year follow-up. The aim of this study was to evaluate the actual CSWT effects in 6 years follow-up period.', 'The subjects were selected exclusively on the basis of inclusion criteria. The total number of patients was 52, out of which control group (n = 11) and the shock wave group (SW group, n = 41) was selected.', 'The wall motion, MPI, nitrate dosage, NYHA classification, SAQ scores, CCS grading, 6 MWT were markedly improved in the long-term (6 years) follow-up for SW group than the control group.
Answer: Following 6 years of follow-up, the CSWT provided agreeable results that improved myocardial function and quality of life in comparing to the month 0 and the control group. These outcomes advise that on a long-term (72 months) CSWT shows better parameters than the control group. These findings highlight that CSWT can improve clinical symptoms, morphology, functions of the heart and quality of life in patients with CHD than the patients just on drug therapy for a long-term.

Context: A computerized physician order entry (CPOE) system with embedded clinical decision support can reduce medication errors in hospitals, but might increase the time taken to generate orders.', 'We aimed to quantify the effects of temporal (month, day of week, hour of shift) and other factors (grade of doctor, prior experience with the system, alert characteristics, and shift type) on the time taken to generate a prescription order.', 'A large university teaching hospital using a locally developed CPOE system with an extensive audit database.', 'We retrospectively analyzed prescription orders from the audit database between August 2011 and July 2012.', 'The geometric mean time taken to generate a prescription order within the CPOE system was 11.75\u2005s (95% CI 11.72 to 11.78). Time to prescribe was most affected by the display of high-level (24.59\u2005s (24.43 to 24.76); p<0.001) or previously unseen (18.87\u2005s (18.78 to 18.96); p<0.001) alerts. Prescribers took significantly less time at weekends (11.29\u2005s (11.23 to 11.35)) than on weekdays (11.88\u2005s (11.84 to 11.91); p<0.001), in the first (11.25\u2005s (11.16 to 11.34); p<0.001) and final (11.56\u2005s (11.47 to 11.66); p<0.001) hour of their shifts, and after the first month of using the system.
Answer: The display of alerts, prescribing experience, system familiarity, and environment all affect the time taken to generate a prescription order. Our study reinforces the need for appropriate alerts to be presented to individuals at an appropriate place in the workflow, in order to improve prescribing efficiency.

Context: Expression of vascular endothelial growth factor (VEGF)-D by tumors is associated with metastasis to lymph nodes in mice. However, there are few reports concerning the clinical significance of VEGF-D protein in human carcinoma.', 'After confirming production of VEGF-D by eight colorectal carcinoma cell lines, we investigated relationships between the expression of VEGF-D protein, lymph node metastasis and postoperative survival in 83 colorectal carcinoma patients. mRNA levels in cell lines were evaluated using the real-time reverse transcriptase-polymerase chain reaction, and protein was detected by Western blotting in cell lines and by immunohistochemistry in resected tissues using an antibody recognizing the processed form of the molecule.', 'Immunohistochemistry showed VEGF-D-positive staining in 26 of the 83 carcinomas (31%). There was a significant relationship between the presence of VEGF-D protein and the incidence of lymph node metastasis (p < 0.01). Multivariate logistic regression analysis revealed that VEGF-D protein expression was an independent factor affecting lymph node metastasis (p < 0.01). Nonetheless, the presence or absence of VEGF-D protein had no significant impact on the survival of the patients (p = 0.15).
Answer: These results suggest that the expression of VEGF-D protein could be useful in predicting the nodal status of colorectal carcinoma patients.
