Additional file 1: Appendix Table 1. PRISMA 2020 Main Checklist. Appendix Table 2. Certainty of evidence for each meta-analysis based on the GRADE approach. Appendix Table 3. Changes in alveolar ridge width (mean ± standard deviation [SD]). Raw data of Radoczy Drajko et al. was also used (measurement at the crestal level). Appendix Table 4. Histological outcomes (mean ± standard deviation [SD]). Appendix Figure 1. Quality assessment based on Cochrane Risk of Bias Tool 2 (RoB 2) for randomized controlled trials. Appendix Figure 2. Quality assessment based on Cochrane risk of bias tool to assess non-randomized studies of interventions (ROBINS-I) for non-randomized studies of interventions. Appendix Figure 3. Funnel plots indicates the presence of statistical heterogeneity and cofounding factors affecting the primary outcome (alveolar ridge width changes). Appendix Figure 4. Funnel plots indicates the presence of statistical heterogeneity and cofounding factors affecting the residual graft proportion (%). Appendix Figure 5. Funnel plots indicates the presence of statistical heterogeneity and cofounding factors affecting the newly formed bone proportion (%). Appendix Figure 6. Funnel plots indicates the presence of statistical heterogeneity and cofounding factors affecting the connective tissue proportion (%). Appendix Figure 7. Pooled mean of residual graft proportion. Neither clinical, nor statistical significant difference can be observed between the subgroups. Appendix Figure 8. Pooled mean of newly formed bone proportion. A statistical significant difference can be observed between the subgroups. Appendix Figure 9. Pooled mean of connective tissue proportion. No statistical significant difference can be observed between the subgroups. Appendix Document 1. Search key. Appendix Document 2. Detailed statistical analysis. Appendix document 3.
