From: Spatiotemporal droplet dispersion measurements demonstrate face masks reduce risks from singing
Boxplot demonstrating maximum droplet number (MDN) across a number of vocal tasks. Sub-table presents median and interquartile range (IQR) of each task, with Wilcoxon signed-rank tests to compare each vocal task with and without a face mask.
