1 · What the graph read from 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.

2 · The registry

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

backgroundDyskalemia involves critical electrolyte abnormalities and increases mortality risk in patients with acute clinical conditions. However, the association between dyskalemia and adverse outcomes in the general population is less well established.

objectiveTo investigate the association of serum potassium levels with mortality and cardiovascular events in the general population and to explore the characteristics of individuals at high risk.

designA prospective cohort study.

participantsA total of 5220 participants aged 50-79 years in the Chinese Multi-provincial Cohort Study. MAIN MEASURES: Serum potassium levels were measured by the ion-selective electrode method. The outcomes were incident cardiovascular disease (CVD), CVD death, non-CVD death, and total death. KEY

resultsOf the 5220 participants, 48.2% were men, and the mean age was 62.3 (SD 7.6) years. Hyperkalemia was found in 8.7% of the participants and was significantly associated with total death (hazard ratio [HR], 1.62; 95% confidence interval [CI], 1.18-2.23) and CVD death (HR, 2.12; 95% CI, 1.25-3.61) after adjustment. Furthermore, the HRs (95% CIs) of hyperkalemia combined with 2 and ≥ 3 risk factors were 2.37 (1.50-3.74) and 4.06 (2.37-6.95) for total death and 3.26 (1.56-6.80) and 8.42 (4.06-17.50) for CVD death, respectively. The 10-year cumulative incidence of total death was 17.4% for participants with 2 or more risk factors.

conclusionHyperkalemia is associated with an increased risk of all-cause and CVD death, and this risk is more pronounced in patients with multiple risk factors. Our findings suggest that early identification and management of hyperkalemia in the general population are warranted.
