The Association of Non-invasive Ventilation and Mortality in COVID-19 Induced Acute Respiratory Distress Syndrome.
Article in Journal of community hospital internal medicine perspectives, 2025. 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
Background: The COVID-19 pandemic caused a major burden on the healthcare system. Since the beginning of the pandemic, the timing of intubation in patients with COVID-19 induced acute respiratory distress syndrome (ARDS) remained an area of debate. Research question: Does a trial of non-invasive ventilation (NIV) in COVID-19 patients worsen mortality in patients intubated due to ARDS? Study design and methods: A single-center, retrospective cohort study of all adult patients (n = 161) with COVID-19 admitted to the ICU between March 2020 through September 2022 with acute hypoxic respiratory failure were included. The group was divided into patients intubated after a trial of NIV (N = 100) and patients intubated without a trial of NIV (N = 61). The primary outcome was to compare the mortality rates between the two groups. Measurements and main results: ICU mortality (defined as death during ICU admission) was higher in patients intubated after a trial of the NIV group compared to those without a trial of NIV (69% vs 52%, p = 0.044). Patients initially treated with a trial of NIV had an odds ratio (OR) of 2.17 for mortality compared to those intubated without a trial of NIV (95% CI 1.04-4.54). ICU length of stay was higher in the intubation after a trial of the NIV group, 11.9 vs 7.7 days (p = 0.001). Patients intubated after a trial of NIV had a longer hospital Length of stay (LOS) (IRR 1.39, 95% CI 1.05-1.85, p = 0.022). However, the duration of mechanical ventilation was similar in the two groups (IRR 1.23, 95% CI 1.93-4.68, p = 0.35). The incidence of pneumothorax, ventilator associated pneumonia (VAP), and venous thromboembolism (VTE) were similar in the two groups. Conclusion: In ARDS, a lung protective strategy with low TV has been proven to improve patient outcomes. The use of a trial of NIV prior to intubation is associated with an increase in mortality.
