Primary outcome – Clinical Attachment Level
| Comparison | Number of sites (primary studies) |
Measure of effect | Effect model | Direction of effect | Follow up | Heterogeneity |
|---|---|---|---|---|---|---|
| Other flap* vs Triangular flap | 68 vs 53 (3) |
WDCAG= 0.05; 95% CI (–0.84, 0.94) |
Random | No difference | At least 3 months | I2= 77.4% |
| Regenerative techniques** vs Control | 195 vs 180 (11) |
MD= 1.98; 95% CI (1.44, 2.52) |
Random | Favors regenerative techniques | 4.5–72 months | I2= 87.3% |
WDCAG weighted mean difference of the clinical attachment gain, MD mean difference, CI confidence interval
