#Indicates the results are the mean value with standard deviation. All other results are the median with interquartile range in parentheses. Pa: one-way ANOVA test. Pb: Kruskal–Wallis H test. TNBC, Triple-negative breast cancer; ADC, Apparent diffusion coefficient.
Bold values indicate statistically significant in P values.
