Pitfalls in radiation oncology. "Myocardial metastasis" in PET-CT after palliative radiation treatment of the left 5th rib.

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
backgroundPositron emission tomography-computed tomography (PET-CT) is a useful diagnostic tool to detect metastases in patients with malignancy. False positives have been reported in cases of inflammation and tissue regeneration. CASE REPORT: Over a period of 2 years, a 32-year-old woman with hepatocellular carcinoma and multiple bone metastases received three treatments of radiation therapy to a bone metastasis in the 5th left rib. Restaging with [18F]fluorodeoxyglucose (FDG) PET-CT showed increased uptake within the cardiac apex highly suspicious for a myocardial metastasis. Because the patient was asymptomatic, additional magnetic resonance imaging (MRI) of the heart was performed demonstrating radiation-associated changes but no evidence for metastases.
conclusionPET-CT is a well-established diagnostic tool in metastatic diseases but its results should always be correlated with the clinical picture of the patient and previous treatments to rule out false positives.
