Incidentally Discovered Pulmonary Hamartoma: A Case Report and Review of the Literature.
Article in Cureus, 2026. 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
Pulmonary hamartoma is a rare benign tumor of the lung. It predominantly affects older males and is frequently peripherally located. On chest radiography, it classically appears as a "coin lesion" exhibiting characteristic popcorn-like calcifications. We report the case of a 62-year-old male patient, a former smoker, being treated for multiple myeloma. A computed tomography (CT) scan revealed a solid, bilobed pulmonary nodule in the lingula measuring 8 mm in the long axis, for which he underwent surgical resection. Macroscopically, the tumor appeared whitish, multilobulated, well-defined, and firm in consistency. Histologically, the lesion is composed of four components: a predominant cartilaginous component with a lobulated architecture, made up of regular chondrocytes; an adipose component, made up of mature adipocytes; a muscular component made up of smooth, non-atypical muscle fibers; and, focally, a fibromyxoid component, associated with an entrapped ciliated respiratory epithelium. Immunohistochemical staining demonstrated positivity for smooth muscle actin and desmin in the smooth muscle cells. Through this case, we discuss the clinical, radiological, histopathological, molecular, and therapeutic aspects of pulmonary hamartoma, as well as the main differential diagnosis, based on data from the literature.
