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
The current coronavirus disease (COVID-19) pandemic remains one of the most serious public health problems. Increasing evidence shows that infection by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes a very complex and multifaceted disease that requires detailed study. Nevertheless, experimental research on COVID-19 remains challenging due to the lack of appropriate animal models. Herein, we report novel humanized mice with Cre-dependent expression of hACE2, the main entry receptor of SARS-CoV-2. These mice carry hACE2 and GFP transgenes floxed by the STOP cassette, allowing them to be used as breeders for the creation of animals with tissue-specific coexpression of hACE2 and GFP. Moreover, inducible expression of hACE2 makes this line biosafe, whereas coexpression with GFP simplifies the detection of transgene-expressing cells. In our study, we tested our line by crossing with Ubi-Cre mice, characterized by tamoxifen-dependent ubiquitous activation of Cre recombinase. After tamoxifen administration, the copy number of the STOP cassette was decreased, and the offspring expressed hACE2 and GFP, confirming the efficiency of our system. We believe that our model can be a useful tool for studying COVID-19 pathogenesis because the selective expression of hACE2 can shed light on the roles of different tissues in SARS-CoV-2-associated complications. Obviously, it can also be used for preclinical trials of antiviral drugs and new vaccines.
