From: Contribution of classification based on ferroptosis-related genes to the heterogeneity of MAFLD
Identification of optimal MAFLD subtypes based on ferroptosis-related genes. A The CDF curves are integrals of the probability density function, which completely describes the probability distribution of a real random variable and is established using a consensus clustering approach. CDF curves of consensus scores based on different subtype numbers (k = 2, 3, 4, 5, 6, 7, 8 and 9) are represented in the corresponding colors. B The CDF Delta area curve of all samples when k = 2. C PCA showed that the two subtypes were clearly distinguished. D Eight ferroptosis-related genes were upregulated in the Cluster 2 subtype of MAFLD.
