I apologize for the confusion earlier

There was a significant difference between the 150 μm interconnection sized scaffolds and the other two kinds of scaffolds at the same time point (correct)

There was no significant difference observed between the three kinds of scaffolds

The 150 μm interconnection sized scaffolds showed no growth

The 100 μm group showed the highest growth

n = 10

n = 5

n = 3 (correct)

n = 20

P < 0.001

P < 0.05 (correct)

P < 0.01
