a Multivariate factor analysis of significant glycan fragments identifies prognostic glycan factors in cancer cell region. b Multivariate factor analysis of significant glycan fragments identifies prognostic glycan factors in stromal region. The numbers on the arrows pointing from the factors to the individual glycan fragments represent the factor loading of each individual glycan fragment on that factor, which quantifies the extent to which the glycan fragment is related to a given factor. Values close to 1 or − 1 represent strong relation, while values close to 0 indicate weak relation. Blue line indicates high score of the factor. Red line indicates low score of the factor
