The effect of serum potassium level on in-hospital and long-term mortality in ST elevation myocardial infarction.
Observational study in International journal of cardiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Current studies evaluating the effect of serum potassium levels on mortality in patients with ST elevation myocardial infarction (STEMI) are lacking. We analyzed retrospectively 3760 patients diagnosed with STEMI. Mean serum potassium levels were categorized accordingly: <3.0, 3.0 to <3.5, 3.5 to <4.0, 4.0 to <4.5, 4.5 to <5.0, 5.0 to <5.5, and ≥5.5mEq/L. The lowest mortality was determined in patients with serum potassium level of 4 to <4.5mEq/L whereas mortality was higher in patients with serum potassium levels of ≥5.0 and <3.5mEq/L. In a multivariable Cox-proportional regression analysis, the mortality risk was higher for patients with serum potassium levels of ≥5mEq/L [hazard ratio (HR), 2.11; 95% confidence interval (CI) 1.23-4.74 and HR, 4.20; 95% CI 1.08-8.23, for patients with potassium levels of 5 to <5.5mEq/L and ≥5.5mEq/L, respectively]. In-hospital and long-term mortality risks were also higher for patients with serum potassium levels of ≤3.5mEq/L. Conversely, ventricular arrhythmias were higher only for patients with serum potassium level of ≤3.5mEq/L. Furthermore, a significant relationship was found between the patient with serum potassium levels of ≤3.5mEq/L and ventricular arrhythmias.
