Data - Deproteinized Bovine Bone vs Hydroxyapatite-Tricalcium Beta Phosphate in Maxillary Sinus Bone Regeneration
Description
A statistical analysis was conducted to compare the effectiveness of bone grafts on new bone formation based on graft type (bovine vs. synthetic) and their application method (used alone or in combination). The mean effect size of bone increase was calculated by averaging the outcomes from the two groups within each study. Descriptive statistics were reported for both comparisons, including mean, standard deviation, and sample size for each group. Normality of the data was assessed using the Shapiro-Wilk test. If normality was confirmed (p > 0.05), independent t-tests were applied to compare the means of the groups. If the normality assumption was violated (p ≤ 0.05), the non-parametric Mann-Whitney U test was used instead. To visualize the differences between groups, boxplots were generated: one comparing the percentage of bone increase between bovine and synthetic grafts, and the other comparing the effects of grafts applied alone versus in combination. To analyze the differences in effects between the two evaluated groups, a scatter plot was used to visually represent the effect estimators of each study. Additionally, the difference between the estimators of Group 2 and Group 1 was calculated for each study. The p-values associated with these differences were included in a comparative table to identify studies with statistically significant differences. A p-value lower than 0.05 was interpreted as evidence of relevant differences between groups. This analysis allowed the identification of possible differential effects of the intervention, providing a basis for interpreting the variability of results across studies.
