The international Hip Outcome Tool 12 questionnaire (iHOT-12): an Italian language cross-cultural adaptation and validation.
Observational study in Journal of orthopaedics and traumatology : official journal of the Italian Society of Orthopaedics and Traumatology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundPatient-reported outcome (PRO) measures are essential for evaluating disease-related quality of life. The International Hip Outcome Tool 12 (iHOT12) assesses various aspects of hip-related symptoms, function, sports participation, and social limitations. This study aimed to adapt and validate an Italian version of the iHOT12 according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. MATERIALS AND
methodsA multicenter observational cohort study was conducted to translate and validate the iHOT-12 into Italian (iHOT-12-ita) and assess its psychometric properties. Following international guidelines, we translated and culturally adapted the iHOT-12-ita. Patients with hip pain included in the study completed the iHOT-12-ita and mHHS-ita questionnaires at three timepoints: initial consultation (T0), 10-20 days later (T1), and at least 2 months after treatment (T2): hip injection, hip arthroscopy or total hip replacement. The evaluation of the iHOT-12-ita psychometric properties was conducted following the COSMIN checklist, assessing its reliability, responsiveness, interpretability, and acceptability.
resultsBetween May 2019 to September 2022, 104 patients were included, from two tertiary hip surgery referral center clinics, they completed both questionnaires and were available for data analysis. The psychometric evaluations revealed robust test-retest reliability on 27 patients at T1, with a Lin coefficient of 0.709 [95% confidence interval (CI) 0.553-0.888] and a high Pearson correlation coefficient of 0.745. At T2 after treatment, there was significant responsiveness (p < 0.001, n = 72), with excellent correlation observed between the iHOT-12-Ita and mHHS-Ita questionnaires (pwcorr = 0.7971). All predefined hypotheses were confirmed.
conclusionsThe Italian iHOT-12-ita proved reliable, valid, and responsive in assessing hip disease-related quality of life. Its implementation in routine clinical practice and research can enhance patient care and research quality in hip preservation surgery for the Italian orthopedic community. LEVEL OF EVIDENCE: II.
