Box-and-whisker plot showing the bias and percent bias in the accuracy-based proficiency testing of creatinine assay conducted by the Korean Association of External Quality Assessment Service from 2011 to 2017. In the box-and-whisker plot, the central boxes represent the values from the 25th and 75th percentile, the middle lines represents the medians, the small empty circles represents outlier values (smaller than the first quartile minus 1.5 times the interquartile range, or larger than the third quartile plus 1.5 times the interquartile range), and the small gray squares represent far outlier values (smaller than the first quartile minus 3 times the interquartile range, or larger than the third quartile plus 3 times the interquartile range).
