ALB and gastric cancer: One MA (Chen et al., 2020) found a statistical difference between the SiJunZi decoction combined with enteral nutrition and enteral nutrition alone in terms of time to flatus (4 RCTs, 260 patients; MD: −9.45 h, 5%CI: −10.76 to −8.13, I2 = 0%, fixed model), length of hospital stay (3 RCTs, 200 patients; MD: −5.22 days, 95%CI: −7.46 to −2.99, I2 = 69%, random model), nutritional status (e.g., albumin, transferrin), and immune function (e.g., immunoglobulin A, immunoglobulin G) of postoperative gastric cancer patients.
