Example Input: Question: Is the diagnosis of inflammatory bowel disease often unsupported in clinical practice?
Answer: Our study showed that the diagnostic prerequisites were widely unfulfilled, although approximately half of the diagnoses were conclusive for inflammatory bowel disease. Thus, in our assessment of clinical practice: (1) clinicians seldom provide suitable clinical and/or endoscopic information for a histological diagnosis and (2) histopathological diagnoses of inflammatory bowel disease are often not supported by morphology.
Example Output: yes

Example Input: Question: Does gluten-free diet appear to induce endoscopic remission of eosinophilic esophagitis in children with coexistent celiac disease?
Answer: The prevalence of eosinophilic esophagitis in patients with celiac disease was 4.4%, confirming a higher than expected prevalence of eosinophilic esophagitis compared with the general population. In patients with celiac disease, a gluten-free diet did not appear to induce remission of coexistent endoscopic and histological features of eosinophilic esophagitis.
Example Output:
no
