Multi-group invariance testing of the knee injury osteoarthritis outcome score for joint replacement scale.
Article in Osteoarthritis and cartilage open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: The Knee Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) scale is commonly used to assess patient progress. Scale structural validity has not been completely assessed. The purpose of this study was to assess the internal consistency, structural validity, and multi-group invariance properties of the KOOS-JR in a large sample of patients receiving knee arthroplasty or non-operative care. Methods: A cross-sectional study using the Surgical Outcome System (SOS) database. Patients receiving care for degenerative knee conditions were included in the study. Internal consistency was assessed using Cronbach's alpha and McDonald's Omega. A confirmatory factor analysis was conducted to confirm scale structure of the KOOS-JR using Results: Internal consistency was acceptable (alpha = 0.83; omega = 0.83). The unidimensional structure of the KOOS-JR exceeded most contemporary model fit recommendations (CFI = 0.976, TLI = 0.964, IFI = 0.976, RMSEA = 0.067). The KOOS-JR was invariant across groups, allowing for comparison of variances and means between sex, age, and intervention groups. Conclusion: The KOOS-JR met or exceeded most of the recommendations for model fit. The scale can be used to assess differences between males and females, middle and older aged adults, and between baseline measures of patients who received total knee arthroplasty or non-operative care.
