Salvage high-dose rate brachytherapy for myxofibrosarcoma of the brachium: a technical report.
Article in Journal of radiation research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
An 80-year-old male presented with T1N0M0 myxofibrosarcoma in or next to the humeral canal, which is located between the biceps and triceps of the right upper arm. Because the tumor was close to critical anatomical structures such as the brachial artery, median nerve and ulnar nerve, it was deemed impossible to perform limb-sparing surgery with an adequate resection margin. Therefore, preoperative external beam radiation therapy (EBRT) followed by limb-sparing surgery was offered. Magnetic resonance imaging taken after 40 Gy/20 fractions of EBRT showed an inadequate response, and limb-sparing surgery was not deemed possible at this point. Amputation of the right arm was offered, but the patient refused. Therefore, salvage high-dose-rate interstitial brachytherapy (HDR-ISBT) was offered. Under local anesthesia and sedation, 14 plastic needles were inserted, and 36 Gy in 6 fractions of HDR-ISBT was performed. Although radiation-induced incomplete paralysis of the median nerve was noted, no local progression or distant metastasis was found on the CT that was taken 2 years after the treatment.
