Statistical analysis
bone defects
The reduction rate of bone defects was statistically compared between the groups using the Kruskal–Wallis test and post-hoc Mann–Whitney U test with Bonferroni correction. Intraclass correlation coefficients were used to estimate the reliability of volumetric measurements. IBM SPSS software (SPSS 25.0, IBM Corp., NY, USA) was used for statistical analysis. Statistical significance was set at p < 0.05.
