Evidence vs. Fear
Highlighting evidence, research, and principles that have been too often forgotten or ignored since March of 2020.
Below are some visual summaries of the balance of mask-related evidence. They are formatted as 24x36 poster-sized pdfs. Please feel free to download, print, and share any part of them! Click to open the full-sized version.
CDC vs. The Evidence
This poster is a organized like a seesaw or teeter totter, with weaker evidence such as modeling and laboratory studies nearer the center, and stronger evidence such as randomized controlled trials and meta-analyses at the ends.
The full-sized version can be zoomed in until even the smallest text is readable. Each block contains a published study in academically-formatted citation. Darker blocks contain studies relating directly to mask efficacy, and lighter blocks contain background information which tends to support or discourage mask use, such as overall COVID-19 transmission risk in various settings, mask side effects, etc.
Collateral Effects of Facemasks
This poster draws on more than 80 published studies which describe adverse collateral effects associated with facemask use, sorted into multiple categories. This list is not exhaustive.
Many studies document multiple categories of side effects, and so appear in more than one column.
The full-sized version can be zoomed in until even the smallest text is readable. Each study and excerpted chart or table is properly-cited in academic format.
This multi-page poster contains summary descriptions and relevant quotes from more than 50 mask studies, including Randomized Controlled Trials, Prospective and Retrospective Observational Studies, Literature Reviews, and Meta-Analyses.
It also includes the excerpted table from Tso and Cowling's 2020 article summarizing pre-2020 public health guidelines in multiple countries, demonstrating that widespread public masking worldwide was neither common nor recommended.
