Translation, cross-cultural adaptation, and analysis of the measurement properties of the Fremantle Knee Awareness Questionnaire (FreKAQ) into Brazilian Portuguese for individuals with knee osteoarthritis.

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
objectiveThis study aimed to translate and cross-culturally adapt the Fremantle Knee Awareness Questionnaire (FreKAQ) into Brazilian Portuguese and evaluate the measurement properties, including internal consistency, construct validity, reliability, and ceiling and floor effects in individuals with knee osteoarthritis (KOA).
methodsTranslation, cross-cultural adaptation, and analysis of measurement properties were performed according to international recommendations. One hundred thirty-four individuals diagnosed with KOA participated in the study. Of these, 30 participated in the validation process of the pre-final version of the FreKAQ. One hundred four were evaluated with the FreKAQ, the Numeric Pain Rating Scale (NPRS), the Pain Catastrophizing Scale (PCS), the International Knee Documentation Committee (IKDC), and the 36-item short-form survey (SF-36). The construct validity was tested using Spearman's correlation coefficient, and ceiling and floor effects were calculated. A subsample of 54 participants participated in the reproducibility assessment. Internal consistency was calculated using Cronbach's alpha. Reproducibility was assessed using the test-retest model using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC).
resultsthe FreKAQ showed a favorable correlation with the construct's intensity and catastrophizing related to pain and activities of daily living (p < 0.01). It also had the functional capacity, pain, social aspects, and emotional aspects of the SF-36 (p < 0.05). Additionally, it presented excellent ICC (0.91) and adequate internal consistency (0.91) with the SEM and MDC scores, respectively, 2.86 and 7.94. There were no ceiling or floor effects.
conclusionThe FreKAQ showed adequate measurement properties in individuals with KOA, indicating its use as an evaluative measure of body perception of the knee.
