Table 1 r2 values for Pearson correlations between PEM scores computed from Gene Expression Atlas (GEA), SAGEmap and TissueInfo expression profiles for six human tissue categories, for which data were available in the three databases.

From: Congruence of tissue expression profiles from Gene Expression Atlas, SAGEmap and TissueInfo databases

  1. a Number of genes compared. SAGEmap and TissueInfo data were only used for genes whose PEM scores were significant by χ2 test (P = 0.05), and only tags that could be mapped unambiguously to UniGene were used. b Two-tailed significance values for Pearson correlation coefficients. c Percentage of genes whose PEM scores have the same sign for the two methods being compared.
