ARP with xenograft (bone graft) vs Extraction alone

Implant failure rate · Adults aged 18 years or older, in good general health (including well-controlled systemic disease), requiring extraction of one or more…

It is very uncertain whether ARP with xenograft (bone graft) changes implant failure rate compared with extraction alone (very low certainty).

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

Prosthesis 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 prosthesis failure compared with no augmentation; GRADE not reported.

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

Vertical bone gain · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)

Autogenous bone graft augmentation at the immediate implant site showed no clear difference in bone gain (vertical - VDH) compared with no augmentation; GRADE not reported.

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

Bone gain (horizontal - HDD) · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)

Autogenous bone graft augmentation at the immediate implant site showed no clear difference in bone gain (horizontal - HDD) compared with no augmentation; GRADE not reported.

Non-resorbable barrier (guided bone regeneration) vs Resorbable barrier + particulate autogenous bone

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

Non-resorbable barrier (guided bone regeneration) led to lower major complications at the implant/donor site compared with resorbable barrier + autogenous bone; GRADE not reported.

Resorbable barrier (guided bone regeneration) vs Non-resorbable barrier (guided bone regeneration)

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

Bio-Oss (anorganic bovine bone) vs Bovine-derived xenograft (Bio-Oss) plus resorbable barrier

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

Bio-Oss (anorganic bovine bone) led to lower augmentation (prosthesis/implant) failure compared with bio-Oss + resorbable barrier; GRADE not reported.

Maxillary sinus lift (augmentation) with long implants vs Short implants (5 to 8.5 mm) without sinus augmentation

Patient satisfaction · Patients with missing teeth and an atrophic posterior maxilla, with residual bone height between 4 and 9 mm below the maxillary sinus

Advance care planning vs usual care

Quality of communication Measured on Quality of Patient‐Clinician Communication About End‐of‐Life Care. Higher score indicates high satisfaction with the quality of communication Assessed after intervention · people with heart failure with or without their surrogate decision‐makers/carers

Vitrectomy vs scleral buckling

Quality of life (satisfaction with vision) at least 3 months after operation · people with simple rhegmatogenous retinal detachments

It is very uncertain whether pars plana vitrectomy (PPV) changes quality of life (satisfaction with vision) at least 3 months after… compared with scleral buckling (very low certainty).
