Diagnosis and management of gastrointestinal SMARCA4-deficient undifferentiated tumors.
Article in Clinical journal of gastroenterology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
SMARCA4-deficient undifferentiated tumors are a rare clinical entity with an aggressive clinical course, poor prognosis, and no standard-of-care therapeutic approach. These have most frequently been documented in the lung and thoracic cavity. There is a growing body of evidence for the role of immunotherapy in SMARCA4-deficient lung cancer, a disease process that historically does very poorly with cytotoxic chemotherapy alone. We present three cases where the primary tumors were instead found within the gastrointestinal system: two originating from the small bowel and one from the esophagus. In all three cases, clinical response was seen with pembrolizumab therapy, with two of the three patients receiving long-term benefit. Our series suggests that anti-PD1 immunotherapy may have promising efficacy for undifferentiated carcinomas of the gastrointestinal tract with SMARCA4 deficiency.
