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: To determine if a strength exercise program prescribed once a week is non-inferior to the same program prescribed three times a week, as measured by change in average walking pain at 3 months post-randomisation, in people with knee osteoarthritis (OA). Design: A parallel two-arm non-inferiority randomised controlled trial, involving 178 people aged ≥45 years, with chronic knee pain consistent with OA. This protocol is reported in accordance with SPIRIT 2025 guidelines. Following baseline assessment, participants are randomised (1:1 allocation ratio) to receive the same home strength exercise program (3 sets of 12 repetitions of 5 lower limb exercises for approximately 3 months) prescribed either i) once weekly or ii) three times weekly. Participants are then randomly assigned to a physiotherapist, who prescribes the exercise program via videoconferencing at the allocated frequency. The primary outcome is the change in knee pain intensity during walking, measured on a numerical rating scale (0-10) at 3 months. Secondary outcomes include the Western Ontario and McMaster Universities Arthritis Index pain and function subscales, quality-of-life, arthritis and exercise self-efficacy, global rating of change, patient-specific functional scale, acceptance of symptoms, muscle strength/power, and willingness to undergo joint replacement. Ethics and dissemination: Approved by the University of Melbourne Human Research Ethics Committee (#2025-33625-70884-3). Dissemination will occur via infographics, lay summaries, conference abstracts, presentations, and journal publications. Clinical trial registration: Australian New Zealand Clinical Trials Registry #ACTRN12625001084471. Prospectively registered on 3/10/2025. Conclusions: Findings will determine whether a less frequently prescribed exercise program is non-inferior to a more frequent exercise program for pain in knee OA.
