‘RNA yield’ (a), ‘A₂₆₀/A₂₈₀’ (b), ‘A₂₆₀/A₂₃₀’ (c), and ‘RIN integrity’ (d) for RNA isolated by the three methodologies with both technicians (Tech A and Tech B). Box-plots of the data are represented. The box with horizontal black line shows the first and third quartiles and the median. The whiskers show 1.5 times the interquartile range. The points show outliers
