Example Input: Question: A 45-year-old man underwent a truncal vagotomy and antrectomy with Billroth II reconstruction, for suffering from a chronic peptic ulcer disease with pylorus-duodenal stenosis. Six weeks after the surgery, he reported that shortly after (less than half an hour) of the ingestions he presented with a nauseating state, asthenia and sweating, dizziness and abdominal cramps, usually accompanied by diarrheal descent. Which of the following is the most appropriate attitude for its initial management? 
 Options:  <1> Apply treatment with a somatostatin analog (octeotide). <2> Follow specific dietary measures. <3> Perform a test treatment with a benzodiazepine. <4> Perform the search for a probable neuroendocrine tumor (eg, carcinoid). <5> Indicate surgical treatment to perform an anti-peristaltic gastro-jejunostomy in Roux-en-Y.
Example Output: 2

Example Input: Question: In a meta-analysis of 15 studies, the incidence of myocardial infarction with the new drug Tromboclean is 10.8% compared to 8% with heparin. The relative risk is 1.35, with a 95% confidence interval of 1.15 to 1.50 and absence of significant heterogeneity between studies (p-value of heterogeneity = 0.95). Point out the CORRECT answer: 
 Options:  <1> The heterogeneity is not significant, which suggests that the results are inconclusive. <2> Trombo Clean presents a risk of myocardial infarction similar to that of heparin. <3> It can not be ruled out with a 95% confidence that Tromboclean reduces the risk of myocardial infarction by 50%. <4> Thromboclean increases the absolute risk of myocardial infarction between 15% and 50%. <5> Heparin presents a significantly lower risk of myocardial infarction than Tromboclean.
Example Output:
