Impact of Country Income Level on Outcomes in Patients with Acute Brain Injury Requiring Invasive Mechanical Ventilation: A Secondary Analysis of the ENIO Study.
Article in Neurocritical care, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundInvasive mechanical ventilation can present complex challenges for patients with acute brain injury (ABI) in middle-income countries (MICs). We characterized the impact of country income level on weaning strategies and outcomes in patients with ABI.
methodsA secondary analysis was performed on a registry of critically ill patients with ABI admitted to 73 intensive care units (ICUs) in 18 countries from 2018 to 2020. Patients were classified as high-income country (HIC) or MIC. The primary outcome was ICU mortality. Secondary outcomes were days to first extubation, tracheostomy, extubation failure, ICU length of stay, and hospital mortality. Multivariable analyses were adjusted for clinically preselected covariates such as age, sex, body mass index, neurological severity, comorbidities, and ICU management. Extubation and tracheostomy outcomes were also adjusted for arterial blood gas values and ventilatory settings.
resultsOf 1512 patients (median age = 54 years, 66% male), 1170 (77%) were from HICs, and 342 (23%) were from MICs. Median age was significantly lower in MICs [35 (range 26-52) vs. 58 (range 45-68) years in HICs]. Neurosurgical procedures (47.7% vs. 38.2%) and decompressive craniectomy (30.7% vs. 15.9%) were more common in MICs, whereas intracranial pressure monitoring (12.0% vs. 51.5%) and external ventricular drain (7.6% vs. 35.6%) were less common. Compared with HICs, patients from MICs had 2.27 times the odds of ICU mortality [p = 0.009, 95% confidence interval (CI) 1.22-4.21]. Frequency of extubation failure was lower in MICs but not significant after adjustment. Patients from MICs had 3.38 times the odds of tracheostomy (p ≤ 0.001, 95% CI 2.28-5.01), 5.59 days shorter mean ICU stay (p < 0.001, 95% CI - 7.82 to - 3.36), and 1.96 times the odds of hospital mortality (p = 0.011, 95% CI 1.17-3.30).
conclusionsIn an international registry of patients with ABI requiring invasive mechanical ventilation, MICs had higher odds of ICU mortality, tracheostomy placement, and hospital mortality compared with HICs, which may be due to difference in neurocritical care resources and management.
