Forrest plots of the performed meta-analysis, meta-analysis for clinical attachment level (CAL) gain, probing pocket depth (PPD) reduction, recession depth (RD) changes, gingival index (GI) scores, plaque index (PI) scores, and bleeding on probing (BOP) scores for up to 6 months and more than 6 months of follow-ups for the without (control) and with (test) the adjunctive use of locally delivered antibiotics during surgical periodontal therapy. Study data, number of analyzed segments, mean difference, standard error (SE) of the difference, relative weight (%), pooled effect estimates for different outcomes, and 95% confidence intervals (95% CI) (bold) from random- and fixed-effect meta-analysis are presented. Heterogeneity was assessed by chi-square test and the I²-statistic. Z overall test statistics, p level of significance
