Example Input: Question: Is vitamin D deficiency in septic patients at ICU admission a mortality predictor?
Answer: In our cohort, septic patients showed a significantly lower vitamin D level than trauma patients in comparison to age cohort patients with the same demographic/clinical characteristics, but no clear relationship between vitamin D level and outcome was found. Further studies with larger samples are needed to clarify the prognostic role of vitamin D and nutraceutical interventions in critically ill patients.
Example Output: no
