In the comparison of mechanical debridement plus antibiotics versus mechanical debridement alone, adjunctive antibiotics were associated with significant improvements in CAL (pooled effect size: −0.84; 95% CI: [−1.55, −0.13]; P = 0.02), PPD (−0.73; [−1.19, −0.27]; P = 0.002) and PS (−3.94; [−7.14, −0.74]; P = 0.02), while the reduction in BOP approached significance (−18.64; [−38.91, 1.63]; P = 0.07).
