Legend:.
The answers to the question “How much do the following factors put a patient at risk for developing peri‐implantitis?” ranged from “1” = “not at all” to “5” = “very much”.
This index was computed by averaging the responses loading on the respective factor in the factor analysis of the responses concerning risk factors.
No index was computed for the responses concerning the implant related risk indicators because Cronbach alpha is 0.426.
