SMARCB1-deficient sinonasal carcinoma: a case report and literature review.
Article in Journal of surgical case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
SWItch/Sucrose Non-Fermentable (SWI/SNF) -related matrix-associated actin-dependent regulator of chromatin (SMARC) subfamily B member 1 (SMARCB1) deficient sinonasal carcinoma (SdSNC) is a rare variant of sinonasal undifferentiated carcinoma (SNUC). A 72-year-old man was referred to our hospital with complaints of left facial pain and nasal obstruction. Computed tomography (CI) revealed a tumor 5.5 cm in size in the left nasal cavity. Atypical cells with eosinophilic cytoplasm proliferating as solid nests and exhibiting necrosis were observed and diagnosed as poorly differentiated carcinoma. Carbon ion radiotherapy was performed. Follow-up CI revealed multiple masses in both lungs. Partial resection of the right lung was performed. Proliferating atypical cells with clear-to-eosinophilic cytoplasm were observed and resembled those in the paranasal sinus tumor. Immunohistochemical analysis indicated a metastatic lung tumor derived from the SNUC revealed completely negative SMARCB1 expression in the nuclei of the tumor cells. SdSNC is difficult to diagnose. However, molecular targeted therapy may be useful. Thus, it is necessary and important to recognize this rare cancer accurately.
