Table 2 Grading the strength of evidence
Comparison of parameters between standard and mini-implants for implant-supported overdenture: | |||
|---|---|---|---|
Outcomes | Parameter values | No. of participants (studies) | Quality of the evidence (GRADE) |
QoL | The mean QoL in the intervention groups was 4.76 lower (6.48 to 3.04 lower) than the control | 177 (2 studies) | ⊕⊕⊝⊝ Lowa,b |
GRADE Working Group grades of evidence High quality: Further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: We are very uncertain about the estimate. | |||
