Hyperbaric oxygen therapy for acute carbon monoxide poisoning patients with coma onset.
Article in European journal of medical research, 2025. 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
objectiveThis study aimed to evaluate the effects of coma on the prognosis and delayed encephalopathy in patients with acute carbon monoxide poisoning (DEACMP) and to analyze the predictive factors affecting the prognosis of these patients.
methodsPatients with acute carbon monoxide poisoning were divided into comatose and non-comatose groups. The primary outcomes included clinical cure and the occurrence of DEACMP. Multivariate logistic regression analysis was performed to identify independent predictors of clinical outcome.
resultsMultivariate analysis indicated that coma (clinical cure: adjusted odds ratio [aOR] 0.24, 95% CI 0.12-0.47; DEACMP: aOR 42.5, 95% CI 7.99-789), longer the time from onset to the first HBOT (clinical cure: aOR 0.43, 95% CI 0.24-0.77; DEACMP: aOR 3.21, 95% CI 1.56-6.78) and abnormal chest CT findings (clinical cure: aOR 0.23, 95% CI 0.12-0.45; DEACMP: aOR 5.36, 95% CI 2.41-12.60) were associated with a lower rate of clinical cure and a higher proportion of DEACMP; and lower age was an independent predictor of clinical cure (aOR 0.96, 95% CI 0.94-0.98), but not of DEACMP (aOR 0.99, 95% CI 0.96-1.01). In comatose patients, both the duration of coma and abnormal chest CT findings were an independent factor for clinial cure (aOR 0.96, 95% CI 0.93-0.99; aOR 0.34, 95% CI 0.15-0.74) and DEACMP (aOR 1.09, 95% CI 1.06-1.14; aOR 4.93, 95% CI 1.67-16.30).
conclusionComa and the duration of coma were significant predictors of clinical cure and DEACMP in patients; the older the patient, the longer the duration of coma, and the longer the time from onset to the first hyperbaric oxygen therapy (> 6 h), indicating that the patient's prognosis is often worse; abnormal chest CT manifestations were also an independent risk factor for a poor patient's prognosis.
