Low-Dose Radiation Therapy for Peripheral Joint Osteoarthritis: Early United States Community Experience With Pain, Function, and Medication Outcomes.

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
Purpose: This study aimed to evaluate the real-world effectiveness and feasibility of low-dose radiation therapy (LDRT) for peripheral joint osteoarthritis (OA) in a United States community oncology setting, focusing on pain, function, and analgesic outcomes. Methods and Materials: We retrospectively analyzed 30 consecutive patients (55 joints) treated with LDRT (3 Gy in 6 fractions; 0.5 Gy per fraction) for OA. Pain was assessed using a 0 to 10 numeric rating scale. Global improvement was captured with the von Pannewitz score (0-4; lower = greater improvement). Analgesic change was abstracted from the medical record. Paired tests compared pre- and posttreatment outcomes. Results: Mean baseline pain was 8.1 ± 1.4, improving to 3.5 ± 1.7 at early follow-up (Δ-4.6; Conclusions: In a community oncology setting, LDRT was feasible and associated with clinically meaningful reductions in pain and analgesic use for peripheral joint OA. These findings support prospective trials to validate benefits and define optimal patient selection and retreatment strategies.
