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.

Abstract

Objective: To compare clinical characteristics and physical activity levels of patients with mild-to-moderate knee osteoarthritis (OA). Methods: A total of 262 individuals with mild-to-moderate knee OA recruited from the Technology, Exercise Programming, and Activity Prescription for Enhanced Mobility (TEAM) Study (NCT04544904) were categorized into two groups: 1) no previous knee injury (NTOA group), or 2) previous knee injury (PTOA group). We collected participants' demographics, Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales, Arthritis Self-Efficacy questionnaire, Intermittent and Constant Osteoarthritis Pain (ICOAP) questionnaire, previous sport participation, radiographic OA features, and medical history. A smartphone application measured daily steps and self-reported physical activity levels were measured using the Global Physical Activity Questionnaire. A 30-s chair-stand and 40-m walk test assessed physical function. Results: The NTOA group was older (62.3 ± 9.0 vs. 58.2 ± 7.4 years, Conclusion: The PTOA group had higher daily steps and better physical and psychological health status than the NTOA group, independent of age and sex. Physical activity interventions may benefit those with NTOA more given their lower activity and greater symptomatology.
