Human co-post pairs are classified into three groups: Tmco≈Tmpost(light gray), (Tmco+2) < Tmpost(orange), and Tmco> (Tmpost+ 2) (cyan). Numbers indicate the count of pairs in each group. The p value was derived from a chi-squared test, assuming the proportions of (Tmco+2) < Tmpost and Tmco> (Tmpost+ 2) are identical.
