Metformin toxicity in the intensive care unit: A case series and review of the literature.
Review in International journal of critical illness and injury science. 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
Metformin toxicity is a life-threatening condition with high morbidity and mortality. Toxicity predominantly occurs in the setting of acute renal dysfunction, as the drug is solely eliminated by the kidneys. While this risk is widely known to clinicians, diagnosing metformin toxicity is challenging because commercially available serum metformin levels require days to weeks to result. Therefore, the intensivist must rely on medical history, clinical presentation, and routine laboratory findings to make the preliminary diagnosis. Treatment of metformin toxicity includes supportive fluid hydration, vasopressors, and emergent hemodialysis (HD). We report three critically ill patients who had near-fatal severe metformin-induced lactic acidosis. Their metformin levels were markedly higher than the toxicity threshold reported by the Federal Drug Agency. These patients made a prompt and complete recovery after the initiation of HD. We also review the pathophysiology, clinical presentation, diagnosis, and treatment of metformin toxicity.
