Retinerad

Could you please confirm the intended meaning or spelling of "retinerad"? As written, it is not a widely recognized term in standard Swedish or English, and I want to avoid delivering inaccurate information. If you can provide the context (for example, whether it relates to medicine/biology, linguistics, law, technology, or a specific field, or if it’s a misspelling of another word), I can draft a concise, neutral wiki-style article under 300 words.
