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

Objective: For people with knee osteoarthritis (OA), step-up is one of the most physically demanding and pain-evoking daily movements. Given the significant role of the prefrontal cortex (PFC) in executive function and pain modulation, our objectives were (1) to assess PFC activation during walking and step-up in people with knee OA and (2) to examine the association of pain and psychological outcomes with changes in PFC activation from walking to step-up. Design: This cross-sectional study included 44 individuals with symptomatic knee OA. Participants completed Knee Injury and Osteoarthritis Outcome Score (KOOS), Pain, Enjoyment of Life, and General Activity (PEG) scale, Patient Health Questionnaire (PHQ-8) for mood, 3-item Pain Catastrophizing Scale (PCS), and Fear-Avoidance Beliefs Questionnaire (FABQ). Oxygenated hemoglobin concentration changes (HbO Results: HbO Conclusion: People with knee OA utilized greater executive control during step-up compared to walking. Similar to stair climbing, step-up is more physically demanding and more frequently impaired than walking. Greater pain catastrophizing was related to smaller increases in PFC activation from walking to step-up, reflecting the availability of fewer executive resources to maintain task performance.
