Fig. 2: RS results in the first and second BC.

a RS results in the second versus the first BC for each patient in the study cohort by nodal status. Red markers/lines represent cases where the second RS was higher than the first, blue markers/lines represent cases where the second RS was lower than the first, and green markers/line represent a case with identical RS results in both tests. b A Box-and-Whiskers plot showing the RS distribution in the first vs the second BC 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 circles represent datapoints that are beyond the 3rd quartile plus 3 × IQR. BC breast cancer.
