Fig. 2From: In-depth metaproteomics analysis of tongue coating for gastric cancer: a multicenter diagnostic research studyStability of the tongue-coating proteome over time. A Collection and sample processing of the samples in the time-series cohort. B The number of human-derived proteins and microbial-derived proteins in the time-series cohort. C The ratio of the abundance of human-derived proteins and microbial-derived proteins at different time points. D The correlation of the abundance of human-derived proteins or microbial-derived proteins between interindividuals and intraindividuals in the time-series cohort. E Correlation coefficient of the abundance of human-derived proteins (left) and microbial-derived proteins (right) in the time-series cohortBack to article page
