Self‐management interventions vs usual care

Respiratory‐related mortality · patients with chronic obstructive pulmonary disease

It is very uncertain whether self‐management interventions including action plans for exacerbations changes respiratory‐related mortality compared with usual care (very low certainty).

Autogenous bone graft augmentation at the immediate implant site vs No augmentation

Implant failure · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)

Autogenous bone graft augmentation at the immediate implant site led to lower implant failure compared with no augmentation; GRADE not reported.

Autogenous bone graft augmentation at the immediate implant site vs No augmentation

Major complications at the implant/donor site · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)

Autogenous bone graft augmentation at the immediate implant site led to lower major complications at the implant/donor site compared with no augmentation; GRADE not reported.
