Paradoxical bradycardia and hemorrhagic shock.
Article in Proceedings (Baylor University. Medical Center), 2019. 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
Hypotension, poor peripheral perfusion, and tachycardia are the most common presenting signs of hemorrhagic shock. Many patients fail to show initial signs of tachycardia and paradoxically present with bradycardia. An 81-year-old man presenting with lower gastrointestinal bleed showed initial vital signs significant for tachycardia and normal blood pressure. After resuscitation with fluids and blood products, his heart rate stabilized to between 64 and 86 bpm. It later dropped to 30 bpm, which improved after administration of atropine. The patient soon experienced two episodes of hematochezia. The paradoxical bradycardia proved to be a false reassurance that the hemorrhage had resolved. Identification of paradoxical bradycardia is important in suspecting ongoing gastrointestinal hemorrhage.
