Serum Sodium Levels Predict Mortality in Elderly Acute Kidney Injury Patients: A Retrospective Observational Study.
Article in International journal of general medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeWe examined the relationship between different levels of serum sodium and mortality among elderly patients with acute kidney injury (AKI).
methodsWe retrospectively enrolled elderly patients from Chinese PLA General Hospital from 2007, to 2018. All-cause mortality was examined according to eight predefined sodium levels: <130.0 mmol/L, 130.0-134.9 mmol/L, 135.0-137.9 mmol/L, 138.0-141.9 mmol/L, 142.0-144.9 mmol/L, 145.0-147.9 mmol/L, 148.0-151.9 mmol/L, and ≥152.0 mmol/L. We estimated the risk of all-cause mortality using a multivariable adjusted Cox analysis, with a normal sodium level of 135.0-137.9 mmol/L as a reference.
resultsIn total, 744 patients were suitable for the final evaluation. After 90 days, the mortality rates in the eight strata were 36.1, 27.8, 19.6, 24.4, 30.7, 48.6, 52.8, and 57.7%, respectively. In the multivariable adjusted analysis, patients with sodium levels <130.0 mmol/L (HR: 2.247; 95% CI: 1.117-4.521), from 142.0 to 144.9 mmol/L (HR: 1.964; 95% CI: 1.100-3.508), from 145.0 to 147.9 mmol/L (HR: 2.942; 95% CI: 1.693-5.114), from 148.0 to 151.9 mmol/L (HR: 3.455; 95% CI: 2.009-5.944), and ≥152.0 mmol/L (HR: 3.587; 95% CI: 2.151-5.983) had an increased risk of all-cause mortality. After 1 year, the mortality rates in the eight strata were 58.3, 47.8, 33.7, 38.9, 45.5, 64.3, 69.4, and 78.4%, respectively. Patients with sodium levels <130.0 mmol/L (HR: 1.944; 95% CI: 1.125-3.360), from 142.0 to 144.9 mmol/L (HR: 1.681; 95% CI: 1.062-2.660), from 145.0 to 147.9 mmol/L (HR: 2.631; 95% CI: 1.683-4.112), from 148.0 to 151.9 mmol/L (HR: 2.411; 95% CI: 1.552-3.744), and ≥152.0 mmol/L (HR: 3.037; 95% CI: 2.021-4.563) had an increased risk of all-cause mortality.
conclusionSodium levels outside the interval of 130.0-141.9 mmol/L were associated with increased risks of 90-day mortality and 1-year mortality in elderly AKI patients.
