Clinical investigation protocol for tinnitus (CIP-t): development and validation of an instrument.

The protocol took about an hour and a half, and the reviewers raised this directly: they suggested shortening it, splitting it over two visits, or doing the muscle and emotional parts only when the history suggests them. Only 13 of the 83 had laboratory tests, so the metabolic findings rest on a small group of people. No one tested positive for vascular tinnitus, so the study cannot show whether that part of the protocol works. Everyone was recruited at one university audiology clinic and already had ear complaints, so they are not representative of all people with tinnitus. The study checked whether the content was valid and whether the protocol could be applied. It measured no treatment outcomes and had no comparison group, so it says nothing about whether patients improve. The authors note the small metabolic sample themselves and call for larger studies and testing in other groups, such as children and adolescents.

The authors declared no financial support and nothing to declare for conflicts of interest, stated in both English and Portuguese.

Do not take "validated" to mean this protocol improves tinnitus. The study asked experts whether the content was sound and whether it could be used, and measured no treatment outcomes. The metabolic part was done on only 13 people and the vascular part on none, so neither is tested in practice.
