Rapid COVID-19 Prognostic Blood Test for Disease Severity Using Epigenetic Immune System Biomarkers.
Article in Delaware journal of public health, 2020. 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
objectiveTo develop a novel whole-blood epigenetic biomarker of immune system status, or EpiMarker, that would indicate whether a person with a recent COVID-19 diagnosis is at risk for severe symptoms including Acute Respiratory Distress Syndrome.
methodsUsing a novel methyl-sensitive restriction endonuclease approach to measure site-specific DNA methylation profiles, immune system phentoype EpiMarkers are identified using a machine-learning computational bioinformatics platform. The result is a diagnostic network of 20 to 40 immuno DNA methylation sites having the greatest predictive power for identifying patients whose COVID-19 disease will likely progress to ARDS requiring ICU/intubation care.
resultsImmune system status in peripheral whole blood provides a sensitive and responsive sentinel signal reflecting how different functional pathways are currently being regulated in a subject. Deciphering this signal status of how immune cells are set to respond provides deep functional information regarding patient health and potential disease phenotypes resulting from a cytokine storm characteristic of a hyper immune inflammatory response to COVID-19 infection.
conclusionsThe ability to identify future potential changes in patient health using this novel EpiMarker technology opens new avenues for defending populations from severe disease risks of Acute Respiratory Distress Syndrome. POLICY IMPLICATIONS: A successful EpiMarker Assay for COVID-19 disease severity risk would allow for two important applications: (1) patients could be triaged early in the course of infection to allow for critical decisions for allocating resources, both in terms of hospital infrastructure (ICU beds, ventilators) and therapeutic drug treatments; and (2) pre-infection, individuals could be screened to identify personnel at low-risk for mission critical assignments (first responders, doctors, nurses, military personnel, etc.) during future pandemics and ongoing battles with viral pathogens like influenza.
