5. Random‐effects metaregression analysis of outcomes PAL, PPD, REC.
Characteristic | Outcome | Studies | Slope estimate (SE) | 95% CI | Slope | P value |
Parallel versus split mouth | PAL | 9 | 0.68 (0.63) | (‐0.81, 2.19) | Emdogain in parallel group trials has higher effect | 0.31 |
Parallel versus split mouth | PPD | 9 | 0.71 (0.66) | (‐0.87, 2.28) | Emdogain in parallel group trials has higher effect | 0.32 |
Parallel versus split mouth | REC | 6 | 0.28 (0.36) | (‐0.72, 1.28) | Emdogain in parallel group trials has higher effect | 0.48 |
CI = confidence interval PAL = probing attachment level PPD = probing pocket depth REC = gingival recession
