Serum glucose/potassium ratio as an indicator of early and delayed outcomes of acute carbon monoxide poisoning.
Article in Toxicology research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundCarbon monoxide (CO) poisoning is a major health problem associated with a high rate of severe morbidity and mortality.
aimsThis study aimed to evaluate the validity of the serum glucose/potassium (Glu/K) ratio as a quick predictor of both early and delayed unfavorable outcomes following acute CO poisoning. PATIENTS AND
methodsThis prospective cohort study included 136 patients with acute CO poisoning admitted at Tanta Poison Control Center, Egypt, between January 2023 and June 2024. The serum Glu/K ratio was calculated for all patients. The primary outcome was a prediction of mortality. Secondary outcomes were the prediction of delayed neurological sequelae (DNS) within six months after CO exposure, the need for mechanical ventilation, and the need for hyperbaric oxygen. A receiver operating curve analysis was applied to test the performance of the Glu/K ratio in predicting acute CO poisoning outcomes.
resultsThe mortality rate was 12.5% of patients with acute CO poisoning. Meanwhile, 14.7% of patients developed DNS. Furthermore, mechanical ventilation was required in 16.9% of patients. An elevated Glu/K ratio was significantly associated with the severity of acute CO poisoning. At a cut-off value of >31.62, the Glu/K ratio demonstrated an AUC of 0.649 for predicting mortality. The Glu/K ratio was employed to predict DNS at a cut-off value of 33.10, with a sensitivity of 60.0%, a specificity of 82.76%, and an AUC of 0.692.
conclusionsEarly Glu/K ratio may be an effective, reliable, and convenient laboratory predictor of mortality, DNS, and the need for mechanical ventilation in patients with acute CO poisoning.
