## Figure 3.
Box and whisker plot showing the absolute bias (μmol/L) for the Jaffe technique. The box represents the 25^{th}, 50^{th} and 75^{th} percentile; the whiskers represent the 5th and 95th percentile. The extremes, defined
as values more than three times the interquartile range, are the signs above and underneath
the whiskers. The grey line represents the 0 μmol/L bias line.
