Significance codes: ** p < 0.01, *** p < 0.001. a: p-values were derived from paired t-tests (for normally distributed differences) or Wilcoxon signed-rank tests (for non-normally distributed differences: BV-T1). b: Effect size (Cohen’s d) was calculated for all comparisons. Abbreviations: BV bone volume, SBAL sinus bone augmentation length, SBAW sinus bone augmentation width, SBAH sinus bone augmentation height, LoA Limits of Agreement.
