Fig. 1: A Box-and-Whiskers plot showing the RS distribution in the first BC in the study cohort vs the RS distribution in the ‘general 21-tested BC cohort’ by nodal status.

The horizontal line represents the median, and the box is drawn from the 1st to the 3rd quartile. The upper whisker represents the highest value below the 3rd quartile plus 1.5 × IQR. The lower whisker represents the lowest value above the 1st quartile minus 1.5 × IQR. Red x symbols represent datapoints that are beyond the 3rd quartile plus 3 × IQR. BC breast cancer.
