Neuroendocrine tumor G1 in sphenoid sinuses: A case report.
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
Neuroendocrine neoplasms (NENs) commonly arise in the gastrointestinal tract, pancreas or lungs. Among NENs, there have been some reports of neuroendocrine carcinoma (NEC) occurring in the paranasal sinuses, but neuroendocrine tumors (NETs) of the paranasal sinuses are particularly uncommon, with only a few cases report available. Furthermore, there have been no comprehensive reports focusing on imaging findings. We herein report a case of paranasal sinus NET G1, along with a literature review of the imaging characteristics. The patient was a 64-year-old woman who was asymptomatic and had been incidentally diagnosed with a sphenoid sinus tumor. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass in the sphenoid sinus with heterogeneous contrast enhancement and destruction of the surrounding bones, including the sphenoid bone, clivus, and petrous bone. The mass had invaded the sella turcica and pushed the pituitary gland upward. The average and minimum apparent diffusion coefficient (ADC) values were 0.796 and 0.601 (× 10
