Summary of findings table
| Determinants of the quality | Overall | Sub analysis | |
|---|---|---|---|
| SRP + ω‐3 | SRP + ω‐3 and ASA | ||
| Study design | RCT | RCT | RCT |
| # Experiments (n = 10) | 10 | 8 | 2 |
| # Meta‐analysis (n = 10) | 10 | 8 | 2 |
| Risk of bias | Low to high | Low | Low to high |
| Consistency | Consistent | Consistent | Rather consistent |
| Directness | Generalizable | Generalizable | Generalizable |
| Precision | Rather precise | Rather precise | Rather precise |
| Reporting bias | Possible | Possible | Possible |
| Magnitude of the effect (Smiley et al., 2015) | Moderate | Moderate | Moderate |
| Strength of the recommendation based on the quality and body of evidence | Moderate | Moderate | Weak |
| Overall recommendation | If SRP is indicated, the use of ω‐3 fatty acids can be considered for a moderate extra added effect on PPD reduction and CAL gain | ||
| The strength of this recommendation is moderate | |||
Abbreviations: CAL, clinical attachment level; PPD, probing pocket depth; RCT, randomized controlled trial; SRP, surgical periodontal therapy; ω‐3, omega‐3 fatty acids.
