Postoperative nutritional status of patients with different digestive tract reconstruction methods after radical gastrectomy. (A) Comparison of SMI, SFI, and VFI values preoperatively and one year after surgery. (B) Rates of changes in the SMI, SFI, VFI, and BMI before and one year after surgery in the B-I, B-II, and R-Y reconstruction groups. (C) Subgroup analysis of patients in each group with preoperative basic BMI values below the median. The rates of changes in the SMI, SFI, VFI, and BMI of patients in different digestive tract reconstruction groups before and one year after surgery. (D) Cluster analysis of the SMI, SFI, VFI, and BMI according to different digestive tract reconstruction methods. The axes represent the two most informative principal coordinates (PCs) of the PCoA analysis, with marginal boxplots describing the distribution in the different groups. The dots in different colors represent the variables analyzed. A pairwise test was used to compare PC1 or PC2 values between the groups, and P-values are shown beside the marginal boxplots. The results of the PERMANOVA to compare dissimilar indexes among the samples are shown in the lower-left corner of the figure. (E) Cluster analysis of preoperative BMIs below the median in each group and combined SMI, SFI, VFI, and BMI values according to different digestive tract reconstruction methods was performed. (F) Correlation between the PNI one year after surgery and the rate of change in BMI during this period. (G and H) Subgroup analysis of the correlation between the PNI one year after surgery and the rate of change in BMI during this period for preoperative BMI values below the median (G) and greater to or equal to the median (H).
