The validity and reliability of the Thai version of the Cochlear Implant Quality of Life questionnaire.
Article in SAGE open medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Improving quality of life is one of the most important outcomes following cochlear implantation, and this can be effectively evaluated using disease-specific questionnaires. However, no such quality of life questionnaire currently exists in the Thai language for cochlear implant recipients. This study aimed to translate and validate the Cochlear Implant Quality of Life questionnaire into Thai. Methods: The original Cochlear Implant Quality of Life questionnaire consists of 35 items across six subdomains. The translation followed Hall's guideline for cross-cultural adaptation. Content validity was reviewed by three experts and 10 healthy participants. Results: After the translation process, the Thai version of the Cochlear Implant Quality of Life demonstrated strong content validity, achieving an Index of Item-Objective Congruence score of 1.0 across all items as assessed by three experts. A review by 10 healthy participants using a five-point Likert scale yielded a mean score of 4.71 (SD = 0.20; range: 4.35-5.00), confirming item clarity and relevance. In testing with 19 cochlear implant users, the Thai version of the Cochlear Implant Quality of Life demonstrated high internal consistency (Cronbach's alpha > 0.6) and good test-retest reliability ( Conclusion: The Thai version of the Cochlear Implant Quality of Life is a valid and reliable instrument for assessing quality of life in adult cochlear implant users. It is suitable for use in clinical settings for Thai-speaking cochlear implant patients.
