Individual reporting probabilities. Distributions of P
(calculated for all individuals separately) rendered as box-and-whisker plots. P
values are provided separately for the four duration categories < 5 minutes, 5 to 15 minutes, 15 to 60 minutes, and 1 to 4 hours. The red box-and-whisker plots show the distributions for all individuals, the olive ones for individuals who reported at least two contacts, the green ones for individuals who reported at least three contacts, the blue ones for individuals with at least four contacts, and the pink ones for individuals with at least five contacts. The whiskers extend from the median line to the highest/lowest value that is within 1.5 times the interquartile range.
