@ChrisACole @IslandPirates77 @elaine_hali @J_D_Klein @HalCranmer If for no other reason than just the statistical uncertainty (not to mention other sources of uncertainty is enormous). For the middle number, surgical masks, the range of reduction reported in the paper is 10%-87%. Turning that into one number is silly, done only for promotion.
@ChrisACole@IslandPirates77@elaine_hali@J_D_Klein@HalCranmer，如果仅仅因为统计不确定性（更不用说其他不确定性来源是巨大的）。对于中等数量的口罩，论文中报告的减少范围为10%-87%。把它变成一个数字是愚蠢的，只是为了提升。
