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.

2 · The registry

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

introductionPain experienced during functional activities, referred to as movement-evoked pain (MEP), is a common and disabling symptom in individuals with knee osteoarthritis (KOA). Unlike pain at rest, MEP may better reflect the real-life burden of KOA and is increasingly recognised as a core outcome in musculoskeletal pain trials. However, its clinical utility remains limited by a lack of evidence on its measurement properties. This study aims to evaluate the test-retest reliability and validity of MEP assessments during functional tasks in individuals with KOA. METHODS AND ANALYSIS: This study includes two components: (1) a test-retest reliability assessment conducted over two sessions separated by approximately 7 days and (2) a cross-sectional analysis of convergent validity. We will recruit 62 participants with symptomatic KOA from the local communities. MEP will be assessed using an 11-point Numeric Rating Scale during five standardised functional tasks: 30-Second Chair Stand Test, One-Step Stair Climb Test, 40m Fast-Paced Walk Test, Timed Up and Go Test and Six-Minute Walk Test. Test-retest reliability will be evaluated using intraclass correlation coefficients (ICC ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee from Shanghai University of Sport (Ref: 102772025RT193). The study protocol was registered on the Open Science Framework (10.17605/OSF.IO/B9N7G). The findings will be disseminated through presentations at national and international scientific conferences and submitted for publication in a peer-reviewed journal.
