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: Collagenous colitis (CC) is a major cause of chronic non-bloody diarrhoea, particularly in the elderly female population. The aetiology of CC is unknown, and still poor is the understanding of its pathogenesis. This possibly involves dysregulated inflammation and immune-mediated reactions in genetically predisposed individuals, but the contribution of genetic factors to CC is underinvestigated. We systematically tested immune-related genes known to impact the risk of several autoimmune diseases for their potential CC-predisposing role.', 'Three independent cohorts of histologically confirmed CC cases (N=314) and controls (N=4299) from Sweden and Germany were included in a 2-step association analysis. Immunochip and targeted single nucleotide polymorphism (SNP) genotype data were produced, respectively, for discovery and replication purposes. Classical human leucocyte antigen (HLA) variants at 2-digit and 4-digit resolution were obtained via imputation from single marker genotypes. SNPs and HLA variants passing quality control filters were tested for association with CC with logistic regression adjusting for age, sex and country of origin.', 'Forty-two markers gave rise to genome-wide significant association signals, all contained within the HLA region on chromosome 6 (best p=4.2×10\Question: Does dense genotyping of immune-related loci identify HLA variants associated with increased risk of collagenous colitis?
Example Output: HLA genotype associates with CC, thus implicating HLA-related immune mechanisms in its pathogenesis.

Example Input: Context: We studied the weight of decision-making on clinical assessment of melanocytic lesions judging benign, atypical, and malignant lesions; common mistakes; and total removal rates, comparing dermatologists with nondermatologists.', 'Of 11,246 histopathology specimens, 3,768 had a clinical assessment of melanocytic lesions. Histopathologic diagnosis served as the gold standard.', 'Benign nevi were assessed most accurately (77%). Dermatologists assessed benign nevi better (p < .0001). The accuracy of clinical assessment in atypical nevi and melanoma was lower (23% and 42%, respectively). Seborrheic keratosis was the most common mistaken diagnosis. Complete removal of clinically benign nevi, atypical nevi, and melanoma was 84%, 90%, and 89%. Decision-making impaired clinical assessement of melanocytic lesions by 5% for dermatologists and 9% for nondermatologists.\Question: Does weight of decision-making impair clinical assessment of melanocytic lesions?
Example Output: The accuracy of clinical assessment of melanocytic lesions is high for benign nevi, with dermatologists outperforming nondermatologists. Clinicians overestimated malignant potential. Complete removal was more frequent in suspicious lesions. Clinical decision-making impaired assessment by 5 to 9%.

Example Input: Context: Orally ingested probiotic bacteria may modulate the immune response and increase antibody titers against enteric infections by bacteria or viruses. Even though positive effects of probiotics on respiratory tract infections have been reported, overall only few studies have examined effects on virus infections concerning organs other than the gastrointestinal tract.', 'It was the aim of the study to investigate whether and how probiotics affect the immune response to a standardized enterovirus challenge (polio) and infections not limited to the gastrointestinal tract in healthy adults.', 'In a randomized, controlled and double-blind study 64 volunteers consumed for 5 weeks chemically acidified clotted milk without bacteria or with 10(10)/serving (Lactobacillus rhamnosus ) GG or Lactobacillus acidophilus CRL431 added. In the second week subjects were vaccinated orally against polio 1, 2 and 3. Polio virus neutralizing serum activity, the primary parameter, was determined by the standard neutralization test (WHO) before and three times after vaccination. Polio-specific IgA, IgG and IgM were detected by ELISAs.', 'Probiotics increased poliovirus neutralizing antibody titers (NT) and affected the formation of poliovirus-specific IgA and IgG in serum. The maximum increase after immunization was about 2, 2.2, or 4-fold higher, respectively, for NT, IgG or, IgA, in volunteers consuming probiotics instead of placebo. No consistent difference was noted between bacterial strains.\Question: Do probiotic bacteria stimulate virus-specific neutralizing antibodies following a booster polio vaccination?
Example Output:
Probiotics induce an immunologic response that may provide enhanced systemic protection of cells from virus infections by increasing production of virus neutralizing antibodies.
