MAO-A expression predicts recurrence-free survival in patients who experienced ER⁻ or TNBC tumors. a Beeswarm plot showing MAO-A expression in 411 grade 3 ER⁻ tumors and 293 grade 3 basal-like tumors; red dots show upper quartile separation range. b Kaplan-Meier survival curves comparing RFS for high- and low-expressing tumors in ER⁻ [HR = 1.74 (1.22–2.47); p = 1.8E-03] and basal-like [HR = 2.15 (1.41–3.28); p = 2.5E-04] cohorts. Analyses were performed using the Km Plotter for Breast Cancer
