Fig. 5From: Analysis of gut microbiota diversity in Hashimoto’s thyroiditis patientsAssociation analysis of gut microbial environmental factors in patients with Hashimoto’s thyroiditis based on genus level. A CCA association analysis of gut microbes in healthy males and females. B CCA association analysis of gut microbes in males and females with Hashimoto’s thyroiditis and normal thyroid function. C CCA association analysis of gut microbes in males and females with Hashimoto’s thyroiditis and abnormal thyroid function. D RDA association analysis of gut microbes in healthy people, normal people with Hashimoto’s thyroiditis, and people with Hashimoto’s thyroiditis and abnormal thyroid function. HCA: healthy population, HT1A: Hashimoto’s thyroiditis with normal thyroid function, HT2A: Hashimoto’s thyroiditis with abnormal thyroid function, HCM: healthy male population, HCF: healthy female population, HT1M: Hashimoto’s thyroiditis in normal males, HT1F: Hashimoto’s thyroiditis in normal thyroid females, HT2M: Hashimoto’s thyroiditis in abnormal thyroid males, HT2F: Hashimoto’s thyroiditis in abnormal thyroid females. CCA: canonical correspondence analysis; RDA: redundancy analysis. Points with different colors or shapes in the figure represent groups of samples under different environments or conditions; dots are used in the figure to represent different samples, and arrows emanating from the origin represent different environmental factors. The length of the environmental factor arrows represents the degree of influence (explained amount) of the environmental factors on species data; the angle between the environmental factor arrows represents positive and negative correlations (acute angle: positive correlation; obtuse angle: negative correlation; right angle: no correlation with sex); the vertical distance from the sample point to the environmental factor arrow and the extended line represents the strength of the influence that an environmental factor has on the sample. The closer the distance between the sample point and the arrow, the stronger the effect of the environmental factor on the sample. In the analysis results, the size of the first axis of Axis_lengths is used to determine the choice of RDA or CCA. If it is greater than or equal to 3.5, the default CCA is displayed, and if it is less than 3.5, the default RDA is displayedBack to article page
