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.
