[求助] 投稿British Journal of Nutrition (BJN)中遇到问题被返回,需要在材料方法中补充内容 已有1人参与

投稿British Journal of Nutrition (BJN),但杂志要求补充以下内容,我不明白是什么意思,还请各位大神指教:
Further to your manuscript submission: the First Editor notes that there is no sample size justification as detailed below and in the Instructions for Contributors.

The methods section must include a subsection that describes the methods used for statistical analysis (see the section on statistical analysis in the Appendix) and the sample size must be justified by the results of appropriate calculations and related to the study outcomes.
Justification of sample size: All manuscripts that report primary research must contain a statistical justification of sample size that is stated explicitly in the Statistics sub-section of the Methods. Manuscripts that do not contain this information will be returned to the authors for correction before peer review. The information required must include, but not be restricted to, the following:-
• Hypothesised effect size with appropriate justification.
• A statement regarding statistical power (typically 80%) and the two-sided significance level (typically 0.05).
• An explanation of how the statistical power was calculated.
• If sample size is determined by the feasibility of recruitment minimally detectable effect sizes should be provided instead of power analysis.
The only exceptions are:-
• Meta-analyses.
• Exploratory or secondary analysis of observational studies based on large sample sizes


Please could you amend your manuscript and send me your amended manuscript and any related files which I will upload accordingly.

稿件中没有说清楚所取样本量的大小以及取这么大的样本量的理由(具体需要说明白的内容可以参考下面列出的以及投稿须知中的内容)。

好像是有关统计的问题
