Measurement data that follows a normal distribution are represented as mean ± standard deviation ('x ± s) and compared between groups using independent sample t-test. Use frequency and percentage (%) to describe count data, and use chi square test between groups with a test level of α=0.05. P<0.05 indicates that the difference is statistically significant.

本数据集包含以下观测指标：营养状况与血液学检验、2002年营养风险筛查（Nutritional Risk Screening 2002，NRS 2002）、住院时长、住院费用及肛门排气时间。所有数据均录入Excel表格，并采用SPSS 27.0版本进行统计分析。符合正态分布的计量资料以均数±标准差（x±s）表示，组间比较采用独立样本t检验；计数资料以频数及百分比（%）进行描述，组间比较采用卡方检验，检验水准设为α=0.05。当P<0.05时，提示组间差异具有统计学意义。
