1 · What the graph read from it

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.

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.

Abstract

backgroundTo evaluate the validity and reliability of the Turkish version of the General Rehabilitation Adherence Scale (GRAS) in individuals with osteoarthritis receiving physiotherapy.

methodsEighty-eight individuals diagnosed with osteoarthritis and undergoing physiotherapy participated in the study. The scale was translated using a forward-backward translation procedure and assessed for content validity. Construct validity was examined using exploratory factor analysis and confirmatory factor analysis to evaluate model fit. Internal consistency was evaluated using Cronbach's alpha coefficients. Test-retest reliability was assessed using intraclass correlation coefficients (ICC).

resultsContent validity indices indicated adequate item relevance. Factor analyses supported a two-factor structure with acceptable model fit indices. Internal consistency was acceptable for the overall scale and subscales. Test-retest reliability demonstrated good to excellent stability over time (ICC > 0.80). The findings indicate that the Turkish GRAS is a psychometrically sound instrument for assessing rehabilitation adherence in individuals with osteoarthritis.

conclusionThe Turkish version of the GRAS is a valid and reliable tool for evaluating adherence behaviors in individuals with osteoarthritis receiving physiotherapy. Its use may assist clinicians in identifying patients at risk of poor rehabilitation engagement and may support individualized intervention planning to optimize functional outcomes.
