1 · What the graph read from it

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.

2 · The registry

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

The natural pathway of antioxidant production is mediated through Kelch-like erythroid cell-derived protein with Cap and collar homology [ECH]-associated protein 1 (Keap1)-Nuclear factor erythroid 2-related factor 2 (Nrf2) system. Keap1 maintains a low level of Nrf2 by holding it in its protein complex. Also, Keap1 facilitates the degradation of Nrf2 by ubiquitination. In other words, Keap1 is a down-regulator of Nrf2. To boost the production of biological antioxidants, Keap1 has to be inhibited and Nrf2 has to be released. Liberated Nrf2 is in an unbound state, so it travels to the nucleus to stimulate the antioxidant response element (ARE) present on the antioxidant genes. AREs activate biosynthesis of biological antioxidants through genes responsible for the production of antioxidants. In some cases of coronavirus disease 2019 (COVID-19), there is an enormous release of cytokines. The antioxidant defense mechanism in the body helps in counteracting symptoms induced by the cytokine storm in COVID-19. So, boosting the production of antioxidants is highly desirable in such a condition. In this review article, we have compiled the role of Keap1-Nrf2 system in antioxidant production. We further propose its potential therapeutic use in managing cytokine storm in COVID-19.
