许多因素影响人类、小鼠和其他哺乳动物的微生物群,但在确定这些因素中哪些具有实际重要性方面仍然存在重大挑战。考虑生物和技术协变量的相对效应大小有助于改进研究设计和生物学结论的质量。必须注意避免可能导致不正确的生物学结论的技术偏差。除P值外,定量效应大小的呈现将提高我们进行荟萃分析和评估潜在相关生物效应的能力。更好地考虑效应大小和统计能力将导致微生物组研究中更可靠的生物学结论。
Many factors affect the microbiomes of humans, mice, and other mammals, but substantial challenges remain in determining which of these factors are of practical importance. Considering the relative effect sizes of both biological and technical covariates can help improve study design and the quality of biological conclusions. Care must be taken to avoid technical bias that can lead to incorrect biological conclusions. The presentation of quantitative effect sizes in addition to P values will improve our ability to perform meta-analysis and to evaluate potentially relevant biological effects. A better consideration of effect size and statistical power will lead to more robust biological conclusions in microbiome studies.
