Naturally Occurring Angiotensin Peptides Enhance the SARS-CoV-2 Spike Protein Binding to Its Receptors.

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
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus responsible for Coronavirus Disease 2019 (COVID-19), utilizes its spike protein to infect host cells. In addition to angiotensin-converting enzyme 2 (ACE2) and neuropilin-1 (NRP1), AXL acts as a spike protein receptor and mediates infection, especially in respiratory cells with low ACE2 expression. Angiotensin II (1-8) can be cleaved into shorter peptides within the biological system. Antibody-based binding assays showed that angiotensin II causes a two-fold increase in the binding between the spike protein and AXL, but not ACE2 or NRP1. While a longer peptide, angiotensin I (1-10), did not affect the spike-AXL binding, shorter lengths of angiotensin peptides exhibited enhancing effects. The
