Stability ranking of reference genes assessed by the comparative ∆CT method. A high delta Ct value indicates instability in the expression of the gene. The dots illustrate the average Standard Deviation (SD) values for each candidate reference gene. Reference genes are ordered from most stable (lowest SD) to least stable (highest SD). Control (n = 8), DED (n = 8), and glaucoma (n = 8) tear samples.
