Blinding not detected. Power Analysis not detected. Sex as a biological variable Briefly, according to this 8–10 weeks old male mice C57BL/6J wild-type and Ahr+/+ and Ahr−/− on C57BL/6J genetic background were administrated. Cell Line Authentication not detected. Table 2: Resources
Antibodies Sentences Resources The program’s protocol included the quantitative analysis of the anti-SARS-CoV-2 IgG antibodies directed against the subunits (S1) and (S2) of the virus spike protein. anti-SARS-CoV-2 IgGsuggested: NoneExperimental Models: Cell Lines Sentences Resources Transactivation Assay: For AhR-mediated transactivation, HepG2 cells were plated at 7.5 × 104 cells/well in a 24-well plate. HepG2suggested: NoneCell culture: Caco-2 cells, a human intestinal epithelial cell line (Sigma-Aldrich) was grown at 37 °C in D-MEM containing 10% FBS, 1% l-glutamine, and 1% penicillin/streptomycin. Caco-2suggested: NoneSARS-CoV-2 yield reduction assay: Vero E6 cells (20,000 cells/well) were seeded in 96-well clear flat-bottom plates and incubated at 37°C with 5% CO2 for 24 h. Vero E6suggested: NoneExperimental Models: Organisms/Strains Sentences Resources Mouse spleen macrophages purification: Spleens were collected from AhR+/+ and AhR−/− mice. AhR−/−suggested: NoneAhR knock out mice (Ahr−/−) on C57BL/6 background and their C57BL/6 congenic littermates wild type (Ahr+/+) were originally supplied by Charles River (Wilmington, MA, USA). C57BL/6suggested: NoneBriefly, according to this 8–10 weeks old male mice C57BL/6J wild-type and Ahr+/+ and Ahr−/− on C57BL/6J genetic background were administrated. C57BL/6Jsuggested: RRID:IMSR_JAX:000664)Software and Algorithms Sentences Resources Primers were designed using the software PRIMER3 (http://frodo.wi.mit.edu/primer3/), using data published in the NCBI database. PRIMER3suggested: (Primer3, RRID:SCR_003139)NCBIsuggested: (NCBI, RRID:SCR_006472)The receptor was treated with the Protein Preparation [34] tool implemented in Maestro ver. Maestrosuggested: (Maestro, RRID:SCR_016748)The docking procedure was realized with the Glide software package (Glide, version 7.1. Glidesuggested: (Glide, RRID:SCR_000187)Results from OddPub: We did not detect open data. We also did not detect open code.

Results from LimitationRecognizer: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.Results from TrialIdentifier: No clinical trial numbers were referenced.
Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).
Results from JetFighter: We did not find any issues relating to colormaps.
