Task: Answer Verification
Input (English): Question: Is early postoperative hyperglycaemia a risk factor for infectious complications and prolonged in-hospital stay in patients undergoing oesophagectomy : a retrospective analysis of a prospective trial?
Answer: Our data indicate that postoperative hyperglycaemia is more likely to be a risk marker than a risk factor in patients undergoing highly invasive surgery for oesophageal cancer. We hypothesize that patients with a low prevalence of vascular disease may benefit less from intensive insulin therapy.
Output (English): no
