The association of movement-evoked pain with cognitive and emotional factors: A cross-sectional study.

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
Background: Movement-evoked pain (MEP) is a feature of knee osteoarthritis impacting individuals' pattern of (in)activity. Little is known about the effect of cognitive or emotional factors on MEP. Objective: To determine associations and explained variances of fear of movement (BFMSO), knee confidence, and situational catastrophizing (SCQ) with MEP and whether associations differ based on the perceived threat of tasks. Design: People with knee osteoarthritis completed the sit-to-stand, stair climb, and 6-min walk tests and rated their peak MEP following each task. Participants ranked tasks from most-to-least threatening regarding anticipated knee pain and completed BFMSO, knee confidence, and SCQ questionnaires for each task. A hierarchical linear regression model was run for each task with MEP as the outcome. Perceived threat of the task was added to the model. Models were adjusted for age, sex, BMI, and resting pain. Results: Data from 81 participants (64% female) with a mean age of 67.5 (SD: 8.4) were included. Adjusted r-squared value for the sit-to-stand, stair climb, and 6-min walk models including BFMSO, knee confidence, and SCQ were 0.37 (F(7,73) = 7.85, RMSE = 17.66), 0.56 (F(7,73) = 15.38, RMSE = 13.92) and 0.48 (F(7,73) = 11.66, RMSE = 17.00), respectively. BFMSO and knee confidence scores were not associated with MEP. SCQ was associated with MEP in all models. The addition of perceived threat ranking to each model did not improve model fit or explained variance. Conclusion: This study provides evidence of momentary cognitive/emotional pain appraisals explaining a moderate amount of variance in MEP in people with knee osteoarthritis, suggesting their potential role in shaping MEP.
