Association of hyponatremia with clinical outcomes in patients admitted with acute pulmonary embolism.
Article in Journal of thrombosis and thrombolysis, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHyponatremia is associated with negative prognosis in several conditions like Congestive heart failure and acute MI (Myocardial Infarction), but its impact on the outcomes in patients with pulmonary embolism (PE) is not well studied. We aimed to study the association of hyponatremia in patients hospitalized with PE.
methodsA retrospective cohort study was designed using data obtained from the 2016 to 2019 combined National Inpatient Sample (NIS) database. Adult patients admitted with PE were identified and stratified based on the presence of hyponatremia. Primary outcomes assessed were, mortality, length of stay (LOS), and Total Hospitalization Charges (THC). Secondary outcomes included a diagnosis of Acute Kidney Injury (AKI), Acute Respiratory Failure (ARF), sepsis, Acute Cerebrovascular accident (CVA), arrhythmias and acute MI. Multivariate linear and logistic regressions were used to adjust for confounders.
resultsThere was a total of 750,655 adult hospitalizations for PE and among them 41,595 (5.5%) had a secondary diagnosis of hyponatremia. Hyponatremia was associated with an increased odds of mortality, 6.31% vs 2.91% (AOR:1.77, p = 0.000, 95% CI: 1.61-1.92), increased LOS, 6.79 days vs 4.20 days (adjusted difference of 2.20 days, p = 0.000, 95% CI: 2.04-2.37), as well as an increase in THC, 75,458.95 USD vs 46,708.27 USD (adjusted difference of 24,341.37 USD, p < 0.001, 95% CI: 21,484.58-27,198.16). Similarly, the presence of hyponatremia was associated with increased odds of several secondary outcomes measured.
conclusionHyponatremia is associated with an increased odds of death and attendant increase in LOS and THC. The odds of several secondary adverse clinical outcomes were also increased.
