Fig. 2From: Peri-tumoural spatial distribution of lipid composition and tubule formation in breast cancerThe group difference in tumour proliferative activity marker Ki-67 between tubule formation Score 2 and Score 3 breast cancer (n = 9,11). Each dot represents the expression of Ki-67 (in percentage), and the dots are organised in two columns corresponding to Scores 2 and 3. The distributions were not normally distributed and the error bars indicate median (interquartile range). The 2-tailed Mann Whitney U test was performed between the groups and p-value is shown. Statistically significant p value (< 0.05) is marked by ‘*’Back to article page
