Stability rankings according to BestKeeper, geNorm, NormFinder, DeltaCt, and RefFinder. Bar graphs showing gene expression stability rankings according to (a) BestKeeper, (b) geNorm, (c) NormFinder (without group identifiers), (d) NormFinder (with group identifiers), (e) DeltaCt, and (f) RefFinder. Genes are organized from the most to least stable. The stability values for each gene as calculated by each algorithm are shown on top of the bars. MAD, average absolute deviation; M value, stability measure; S value, stability value; SDavg, mean standard deviation; GMR, geometric mean of the rankings
