Continuous weight loss occurred for up to 3 years. Women and men had a similar risk of malnutrition after 3 years (OR 0\u00b785 (95 per cent confidence interval 0\u00b724 to 2\u00b798)). In overweight patients (preoperative body mass index at least 25 kg\/m2) the risk of malnutrition was increased almost fivefold at 6 months (OR 4\u00b790 (2\u00b727 to 10\u00b759)) and 3 years (OR 4\u00b760 (1\u00b780 to 11\u00b778)). There was no difference in weight loss at 6 months between survivors and those who died between 6 months and 3 years after surgery (OR 1\u00b711 (0\u00b764 to 1\u00b794)).<\/jats:p>\n
