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
objectiveThe COVID-19 pandemic is progressing rapidly, sending the world into a great panic. Healthcare professionals have responded by embarking on a concerted search for therapies to cure and prevent COVID-19. Recently, interferon (IFN) has emerged as a potential therapy as it is associated with reducing lung inflammation and suppressing viral replication. This research paper assessed the efficacy of high-dose nebulized IFN α 2b in severe COVID-19 pneumonia.
methodsThis is a retrospective study. It commenced on April 9 and ended on June 17, 2020. Researchers selected participants from hospitalized patients aged 18 years and above who were diagnosed with severe COVID-19 pneumonia. Other inclusion criteria were bilateral pneumonia on lung or chest X-ray scan and severe respiratory distress. SMART-COP, which is a risk stratification scoring tool, and radiologic severity index (RSI) were used to assess pneumonia severity. Patients in the treatment cohort received nebulized IFN α 2b at a dose of 10 million IU every 12 hours for 5 days, in addition to standard treatment. Patients in the control cohort received standard treatment only.
resultsSeventy-three patients met the inclusion criteria; 37 were included in the treatment cohort and 36 in the control cohort. Mechanical ventilation was needed in 14 of 36 (38.9%) patients in the control cohort, compared with 6 of 37 (27.4%) patients in the treatment cohort (HR 5.62 [95% CI 1.81-17.48]; P = .003). For pneumonia severity, there was a hazard ratio (HR) of 3.72 [95% CI 1.74- 7.98]; P = ·.01. After 5 days of treatment, chest X-rays indicated significant beneficial changes in the treatment group (HR 2.24 [CI 1.05-4.79]; P = .036). Multivariate analysis revealed that pneumonia severity and RSI remained higher in the control group. The HR was 3.44 [95% CI 1.49-7.94]; P = .004 and 2.26 [95% CI 0.99-5.16]; P = .05, respectively. There was an increase in liver aminotransferases in 5 (14%) participants in the control cohort and 3 (8%) participants in the treatment cohort.
conclusionHigh-dose nebulized IFN α 2b has potential efficacy in mitigating severe COVID-19 pneumonia. This study established that administering high-dose nebulized IFN α 2b significantly reduces pneumonia severity in COVID-19 patients. We also found a strong relationship between using nebulized IFN α 2b and reduced need for mechanical ventilation among patients with severe COVID-19 pneumonia. However, a well-designed control trial is needed to confirm the drug's efficacy in reducing the COVID-19 pneumonia severity.
