Table 1 Two-by-two contingency table

From: Metabolomic correlation-network modules in Arabidopsis based on a graph-clustering approach

  within DPClus cluster without DPClus cluster total
KEGG pathway a b a+b
non-KEGG pathway c d c+d
totals a+c b+d n
  1. a is the number of metabolites in the KEGG pathway belonging to the DPClus cluster, a+b indicates the total number of metabolites in the KEGG pathway, a+c the number of metabolites in the DPClus cluster, and n the total number of metabolites in the profiling data. Rows reflect presence/absence within the KEGG pathway. Columns contain each of the 2 DPClus clusters. For each KEGG pathway the metabolites belonging to the 2 comparison groups are shown.
