Summary treatment effects from network meta-analysis and pairwise meta-analysis for alveolar bone (a), cementum (b), and periodontal ligament regeneration (c) likelihood. Comparisons should be read from left to right. The estimate is located at the intersection of the column-defining treatment and the row-defining treatment. The lower triangles of the league tables represent the NMA results, and the upper triangles are the pairwise meta-analysis results. For the NMA and pairwise meta-analysis results, an SMD value higher than 0 favors column-defining treatment. For SMDs of comparisons in the opposing direction, the opposite numbers should be taken. Significant results are bold and underscored. NA = not applicable, no preclinical studies making direct comparisons
