Summary of dietary records and validating measures in urine.

All values are expressed as medians (IQR) (n = 20). Parameters with different letters (a, b, c) in superscript are significantly different between the dietary interventions, test. Friedman and Wilcoxon tests were used to evaluate the results, except for urinary N and urea. Due to missing, values an unstructured linear mixed model was applied using treatment as fixed effect. P-values refer to Friedman tests.

所有数值均以中位数（四分位距，Interquartile Range，简称IQR）表示，样本量n=20。上标带有不同字母（a、b、c）的参数提示各饮食干预组间存在显著差异。除尿氮（urinary N）与尿素外，其余指标均采用弗里德曼检验（Friedman test）与威尔科克森检验（Wilcoxon test）进行评估。鉴于存在缺失值，本研究采用以干预措施为固定效应的非结构化线性混合模型进行分析。所有P值均对应弗里德曼检验的结果。
