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: An association between mitral valvar prolapse and low body mass index has been proposed. The goal of this study was to evaluate this suggested association using two independent and large databases. For comparison, we evaluated the association, if any, between bicuspid aortic valve and low body mass index.', 'We retrospectively analyzed, using uni- and multivariate analysis, 1742 echocardiograms that were performed as a part of a cardiac screening of teenage athletes and 24,265 echocardiograms performed between 1984 and 1998 for various clinical indications.', 'The first database included a total of 12,926 (53%) female and 11,339 (47%) male patients. The second database included a total of 1172 male (67%) and 570 female (33%) high school athletes. Mitral valvar prolapse was independently associated with low body mass index in addition to mitral regurgitation in both data bases. An index less than 30 occurred in 78 of 13,874 (0.6%) as opposed to 7 of 3236 (0.2%) in the echo data base, p equal to 0.03, odds ratio: 2.4 confidence intervals: 1.1-5.2, and an index less than 20 occurred in 7 of 354 (2%) as opposed to 6 of 944 (0.6%) in the athletic data base, p equal to 0.03, odds ratio: 3.2 confidence intervals: 1.05-9.5. The finding of a bicuspid aortic valve did not have any association with low body mass index.\Question: Is mitral valvar prolapse significantly associated with low body mass index in addition to mitral and tricuspid regurgitation?
Example Output: In our two independent databases, mitral valvar prolapse was independently associated with low body mass index in addition to mitral and tricuspid regurgitation. The cause of this association remains unknown.

Example Input: Context: Intracellular pathogens have developed elaborate strategies for silent infection of preferred host cells. Chlamydia pneumoniae is a common pathogen in acute infections of the respiratory tract (e.g. pneumonia) and associated with chronic lung sequelae in adults and children. Within the lung, alveolar macrophages and polymorph nuclear neutrophils (PMN) are the first line of defense against bacteria, but also preferred host phagocytes of chlamydiae.', 'We could show that C. pneumoniae easily infect and hide inside neutrophil granulocytes until these cells become apoptotic and are subsequently taken up by macrophages. C. pneumoniae infection of macrophages via apoptotic PMN results in enhanced replicative activity of chlamydiae when compared to direct infection of macrophages, which results in persistence of the pathogen. Inhibition of the apoptotic recognition of C. pneumoniae infected PMN using PS- masking Annexin A5 significantly lowered the transmission of chlamydial infection to macrophages. Transfer of apoptotic C. pneumoniae infected PMN to macrophages resulted in an increased TGF-ss production, whereas direct infection of macrophages with chlamydiae was characterized by an enhanced TNF-alpha response.\Question: Does chlamydia pneumoniae hide inside apoptotic neutrophils to silently infect and propagate in macrophages?
Example Output: Taken together, our data suggest that C. pneumoniae uses neutrophil granulocytes to be silently taken up by long-lived macrophages, which allows for efficient propagation and immune protection within the human host.

Example Input: Context: High anxiety has been reported in patients with drug hypersensitivity reaction (DHR); however, its relationship with the test results was not studied previously.', 'We aimed to investigate the association of patient anxiety with the results of drug tests together with the other contributing factors.', 'Sixty-seven patients were included in the study between November 2012 and April 2013, in whom drug tests were performed after clinical evaluation and application of the Penn State Worry Questionnaire (PSWQ).', 'The mean ± standard deviation (SD) age was 43.5 ± 12.9 years, and 73.1% of the patients were females. The patient group had significantly higher mean ± SD PSWQ score than 35 control subjects without histories of DHRs and major psychiatric disorders (47.95 ± 14.64 versus 40.22 ± 11.86, p = 0.008). However, the mean ± SD. PSWQ score of the patients with positive drug test results was not significantly different from the patients with negative drug test results (46.06 ± 13.41 versus 50.47 ± 18.02, p = 0.32). Panic attack symptoms were more common in the reactions with positive test results than in the reactions with negative test results (74.0% versus 48.9%, p = 0.01). However, presence of panic attack symptoms [odds ratio (OR): 1.25, 95% confidence interval (CI): 0.44-3.54; p = 0.67] was not found independently associated with positive test results in the multiple logistic regression model.\Question: Does evaluation of anxiety levels and factors associated with positive test result in patients with drug hypersensitivity?
Example Output:
Patients with DHR have high levels of anxiety; however, this is not related to the results of drug tests. Because panic reaction symptoms may accompany the objective symptoms of DHR, a complete clinical work-up is required before deciding whether the reaction is related to panic or a "true DHR."
