Bland-Altman plots for investigating the level of agreement between RNA extraction kits. Each plot shows the differences between the two kits against the averages of the two kits. The lines represent the mean differences and upper and lower limits of agreement (LOA, mean differences ±1.96SD). a Comparison of RNA yield (ng/μl) of samples extracted with High Pure FFPE RNA Micro Kit and RNeasy® FFPE kit. b Comparison of purity (A260/A280) of samples extracted with High Pure FFPE RNA Micro kit and RNeasy® FFPE kit. c Comparison of RIN-values of samples extracted with High Pure FFPE RNA Micro kit and RNeasy® FFPE kit. d Comparison of RNA yield (ng/μl) of samples extracted with RNeasy® FFPE kit and AllPrep® DNA/RNA FFPE kit. e Comparison of purity (A260/A280) of samples extracted with RNeasy® FFPE kit and AllPrep® DNA/RNA FFPE kit. f Comparison of RIN-values of samples extracted with RNeasy® FFPE kit and AllPrep® DNA/RNA FFPE kit
