Fig. 3: OncotypeDx Recurrence Score (RS) according to Ki67-grade combined risk.
From: Systematic evaluation of scoring methods for Ki67 as a surrogate for 21-gene recurrence score

Categories (low risk = grade 1 or Ki67 hotspot <20, high risk = rest). Box plot is drawn as follows: each box represents interquartile range with the inside line representing median value. Whiskers represent maximum (75th percentile + 1.5 × interquartile range) and minimum (25th percentile–1.5 × interquartile range) values. Each dot represents individual samples.
