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
Intra-articular metastasis of the shoulder (IMS) is extremely rare. Here, we report three cases of IMS from lung cancer treated with stereotactic body radiotherapy (SBRT) using CyberKnife. Case 1 involved a 50-year-old man with IMS of small-cell lung cancer who developed right shoulder pain that worsened over two weeks. The IMS was treated with SBRT in five fractions over eight days (treatment volume: 19.4 mL; prescribed dose: 30 Gy; maximum dose: 51.7 Gy; treatment time: 35 minutes per fraction). Pain relief occurred immediately and resolved completely within 10 days of initiating SBRT. Pain did not recur until the patient died five months later. Case 2 involved a 66-year-old woman with IMS of lung adenocarcinoma who developed left shoulder pain that worsened over one month. The IMS was treated with SBRT in three fractions over three days (treatment volume: 7.5 mL; prescribed dose: 30 Gy; maximum dose: 44.1 Gy; treatment time: 37 minutes per fraction). Pain relief occurred immediately and resolved completely within four days of initiating SBRT. The pain did not recur until the patient died 22 months later. Case 3 involved a 73-year-old man with IMS of lung adenocarcinoma who developed right shoulder pain that worsened over one month. The IMS was treated with SBRT in three fractions over four days (treatment volume: 6.1 mL; prescribed dose: 30 Gy; maximum dose: 46.2 Gy; treatment time: 32 minutes per fraction). Pain relief occurred immediately and resolved completely within one week of initiating SBRT. The pain has not recurred in the nine years and three months since SBRT. No SBRT-related adverse events occurred in any of the cases. IMS should be included in the differential diagnosis of cancer patients with shoulder pain. SBRT may be a useful palliative treatment for such cases.
