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

Many patients with coronavirus disease 2019 in intensive care units suffer from cytokine storm. Although anti-inflammatory therapies are available to treat the problem, very often, these treatments cause immunosuppression. Because angiotensin-converting enzyme 2 (ACE2) on host cells serves as the receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), to delineate a SARS-CoV-2-specific anti-inflammatory molecule, we designed a hexapeptide corresponding to the spike S1-interacting domain of ACE2 receptor (SPIDAR) that inhibited the expression of proinflammatory molecules in human A549 lung cells induced by pseudotyped SARS-CoV-2, but not vesicular stomatitis virus. Accordingly, wild-type (wt), but not mutated (m), SPIDAR inhibited SARS-CoV-2 spike S1-induced activation of NF-κB and expression of IL-6 and IL-1β in human lung cells. However, wtSPIDAR remained unable to reduce activation of NF-κB and expression of proinflammatory molecules in lungs cells induced by TNF-α, HIV-1 Tat, and viral dsRNA mimic polyinosinic-polycytidylic acid, indicating the specificity of the effect. The wtSPIDAR, but not mutated SPIDAR, also hindered the association between ACE2 and spike S1 of SARS-CoV-2 and inhibited the entry of pseudotyped SARS-CoV-2, but not vesicular stomatitis virus, into human ACE2-expressing human embryonic kidney 293 cells. Moreover, intranasal treatment with wtSPIDAR, but not mutated SPIDAR, inhibited lung activation of NF-κB, protected lungs, reduced fever, improved heart function, and enhanced locomotor activities in SARS-CoV-2 spike S1-intoxicated mice. Therefore, selective targeting of SARS-CoV-2 spike S1-to-ACE2 interaction by wtSPIDAR may be beneficial for coronavirus disease 2019.
