Table IV. Ranking of individual miRNAs of different groupings by different algorithms. Low values indicate more stable miRNAs. The two lowest scores for each algorithm in the spike-in control and the endogenous miRNAs groups are shown in bold.

DC: Delta-Ct method; BK: BestKeeper; NF: Normfinder; GN: GeNorm; CR: RefFinders comprehensive ranking calculating a geometric mean based on the rankings from the other four algorithms.
