Explain this table (shown in picture) from a study with the help of the information below and additional information from the article (shown in picture): Primary liver cancer is one of the most prevalent life- threating diseases in China, and liver resection is the major therapy for this malignancy. Recently, various methods have been advocated perioperatively to maintain liver function and promote liver regener- ation after liver resections. These include systemic interventions such as antibiotics in perioperative period and methods to improve general health and the immunity of the individual such as prebiotics and probiotics. Among them, nutritional support is also a vital approach to protect liver function. It has been demonstrated that a good preoperative nutri- tional status could reduce the postoperative morbidity or mortality and consequently the costs of care after surgery. Moreover, malnutrition is frequent in patients suffering from malignant liver disease. Optimization of…
