Large Pleural Effusion Secondary to Primary Signet-Ring Cell Adenocarcinoma of the Lung.
Article in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Primary signet-ring cell adenocarcinomas (SRCA) that occur outside the gastrointestinal tract are rare with few cases reported in the literature. They carry a poor prognosis and can be a challenge to diagnose. In this case report, we present the case of a 69-year-old female who presented to our hospital with a large left-sided pleural effusion. The findings seen on histopathology and immunohistochemistry (IHC) staining of the pleural fluid were consistent with primary signet-ring cell adenocarcinoma of the lung, and further investigations excluded a secondary source of malignancy. To the best of our knowledge, this is the first reported case of pleural effusion without an underlying lung mass diagnosed as primary signet-ring cell adenocarcinoma of the lung. Given how rare primary signet-ring cell adenocarcinoma of the lung is, it is important for physicians to carry out a comprehensive diagnostic workup to differentiate between primary and metastatic signet-ring cell adenocarcinoma as this will determine prognosis and treatment.
