Porosities of Samples scaffolds.

Scaffolds	Porosity (%)
P1	80 ± 0 a,b,c
P2	90 ± 2.7 a
P3	85.71 ± 0 a,b
P4	94.06 ± 0.7 a
P5	87.85 ± 6.1 a
P6	83.33 ± 2.4 a,b
P7	55.56 ± 9.6 c
P8	91.40 ± 1.5 a
P9	73.89 ± 6.7 a,b,c
P10	58.73 ± 13.8 b,c

Note: the data is presented as mean ± standard deviation; different letters indicate significant differences with a significance level of 99.9%. In these results, the table shows that group A contains samples P1–P6 and P8 and P9, group B contains samples P1, P3, P6 and P9, and P10, and group C contains samples P1, P7, P9, and P10. Samples P1 and P9 are in all three groups. The differences between the means that share a letter are not statistically significant.
