From: A pilot study of coughing into the shirt to disrupt respiratory pathogen transmission
Cough maximal plume area (MPA) pixel counts across all participants (1 through 5) and all maneuvers: unobstructed, elbow, mask, and shirt. The shirt maneuver generally shows cough MPA on par with the mask maneuver, except for Participant 4, which shows many white pixels that escape an untucked shirt or placement of the mouth relative to the shirt collar
