Risk of Hyponatremia in Patients with Aneurysmal Subarachnoid Hemorrhage Treated with Exogenous Vasopressin Infusion.
Article in Neurocritical care, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundVasopressin is one of the vasopressors used to augment blood pressure in subarachnoid hemorrhage (SAH) patients with clinically significant vasospasm. The purpose of the present study was to determine whether the administration of vasopressin to a population of SAH patients was an independent predictor of developing hyponatremia.
methodsA retrospective review on the health records of 106 patients admitted to the University of Alberta Hospital Neurosciences ICU, Edmonton AB, Canada, with SAH from June 2013 to December 2015 was conducted. Serum sodium changes in patients receiving vasoactive drugs were compared. In addition, independent predictors for hyponatremia (Na < 135 mmol/L) were determined using a multivariate logistic regression model.
resultsPatients treated with vasopressin in addition to other vasoactive drugs had significantly higher sodium changes compared to those treated with other vasoactive drugs (-4.7 ± 6 vs -0.1 ± 2.4 mmol/L, respectively, p value 0.001). Hyponatremia occurred in 14 patients (70 %) treated with vasopressin, 10 patients (44 %) treated with vasoactive drugs other than vasopressin (p value 0.081), and 24 patients (38 %) who did not receive any vasoactive drug (p value 0.013). In multivariate logistic regression analysis, when adjusting for disease severity, age, sex, aneurysm location, and treatment, vasopressin was associated with hyponatremia (OR 3.58, 95 % CI, 1.02-12.5, p value 0.046).
conclusionsThe results of the present study suggest that hyponatremia may be more common in SAH patients treated with exogenous vasopressin compared to those who did not receive it. Serum sodium should be monitored closely when vasopressin is being used in the SAH population. Further studies are needed to confirm the effect of exogenous vasopressin on serum sodium levels in SAH populations.
