An uncommon presentation of abdominal mass in an infant: A case report of fetus in fetu.
Article in Radiology case reports, 2025. 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
Owing to the rare existence of fetus in fetu (FIF) with an incidence of one per 500,000 live births worldwide, embryologically it is characterized as diamniotic, monochorionic, monozygotic twins partially developing within the twin body. We present a case of a 10-month-old female suffering from progressively increasing abdominal distention and an immobile abdominal mass which was highlighted on contrast-enhanced computed tomography (CECT) consisting of soft tissue, gaseous, and fluid components. It was deciphered after surgical intervention as a stunted fetus characterized by the presence of structures such as the auricle, eye impressions, limb, vertebral column, brain, and gastrointestinal tissue. Such findings suggest the case of a fetus in fetu. Fetus in fetu must be considered as a differential diagnosis among infants and young children presenting with abdominal distention. Such a presentation must never be overlooked and probed clinically and radiologically, followed by surgical intervention to relieve the pressure effect over the viscera and abdomen.
