From: Clinical outcomes following surgical treatment of peri-implantitis at grafted and non-grafted implant sites: a retrospective analysis

Group	mean	SD	median	min.	max.	mean	SD	median	min.	max.
Non-grafted sites	60.64	40.81	67.0	0	100	54.88	43.65	67.0	0	100
Grafted sites	77.45	30.92	87.25	0	100	74.96	38.95	100	0	100

The differences between the groups did not yield a significant difference (patient level p = 0.778, implant level p = 0.515, chi-square test)
