In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Optimistic people report a higher quality of life, engage in more active coping and adopt more health-promoting behaviors than people low in optimism, ie, pessimism. We evaluated whether pessimists are more likely to show progression in carotid disease than optimists.', 'A total of 209 middle-aged healthy premenopausal women enrolled in an epidemiological study of cardiovascular risk factors and had carotid scans 10.4 years and 13.5 years later when they were at least 5 years postmenopausal. Women completed the Life Orientation Test (LOT), a measure of pessimistic and optimistic attitudes, at study entry and at the time of the first carotid scan. Analyses evaluated the association of LOT scores and change in carotid intima medial thickness (IMT) across 3 years.', 'Multiple linear regression analyses showed that the higher the pessimism scores at study entry, the greater the increase in mean IMT (beta = 0.17, p <.007). A comparison of those in the lowest quartile of LOT scores (most optimistic) with those in the other three quartiles showed that the most optimistic group had less progression than the remaining more pessimistic women (mean percent increase = 1.3 and 6.0 for mean IMT, F = 15.4, p <.001). Women who were chronically optimistic at study entry and at the first carotid scan (bottom quartiles at both times) had less progression in mean IMT than did those who were chronically pessimistic (top quartiles at both times).\Question: Do optimistic attitudes protect against progression of carotid atherosclerosis in healthy middle-aged women?
Example Output: Optimistic women are less likely to show progression of carotid disease in mid-life than are pessimists.

Example Input: Context: The present analyses intend to clarify if gender and puberty modify the relationship between bone development (modeling and remodeling) and fat mass at the forearm.', 'Data were collected from participants (139 males, 157 females, age = 5-19 years) of the Dortmund Nutritional and Anthropometric Longitudinally Designed study in a cross-sectional investigation. The main outcome measures were total and trabecular bone mineral density (BMDtot and BMDtrab), strength strain index (SSI) and parameters associated with modeling (cortical area, CA; periosteal circumference, CP) and remodeling (cortical bone mineral density, BMDcort, endosteal circumference, CE) were analyzed in their relationship to cross-sectional fat (FA) and muscle area (MA) at the forearm.', 'BMDtot was correlated with FA in pubertal males (r = -0.25). BMDtrab was contrarily predicted by FA in pubertal males and females (r = -0.28 vs. 0.31). FA was correlated with BMDcort (r = -0.32) and CE (r = 0.26) in pubertal females. MA was positively correlated with CA, CP and SSI.\Question: Is local body composition associated with gender differences of bone development at the forearm in puberty?
Example Output: Modeling and bone strength were primarily predicted by MA. Markers of remodeling were positively correlated with FA in pubertal females, but not in prepubertal individuals and pubertal males. Therefore, gender and puberty modify the relationship between FA and bone development.

Example Input: Context: To investigate the role of preoperative neutrophil-to-lymphocyte ratio (NLR) in prediction of response to first-line platinum-based chemotherapy and survival outcome in serous ovarian cancer (SOC) patients.', 'Clinicopathologic data were reviewed for patients with SOC treated with primary cytoreduction followed by platinum-based chemotherapy. The correlations of NLR value with clinicopathological features, clinical response to chemotherapy, and survival outcome were further explored.', 'High preoperative NLR was significantly associated with advanced FIGO stage, histological grade, increased serum CA-125 level, and positive lymph node metastasis (P < 0.05, respectively). SOC patients in the third and fourth NLR quartile had significantly lower complete response rates compared to those in the first NLR quartile. In addition, survival analysis identified NLR as an independent prognostic factor for both PFS (HR 2.262, 95% CI 1.342-3.811; P = 0.002) and OS (HR 3.254, 95% CI 1.741-6.084; P < 0.001) in SOC patients.\Question: Does preoperative neutrophil-to-lymphocyte ratio predict response to first-line platinum-based chemotherapy and prognosis in serous ovarian cancer?
Example Output:
Our findings indicated that high levels of preoperative NLR might be a potential biomarker of worse response to first-line platinum-based chemotherapy and poor clinical outcomes in patients with SOC. Further validation of this easily available parameter as a potential stratification tool in prospective studies should be encouraged.
