Extended Data Fig. 4: Strain-sharing rate in reciprocated versus unreciprocated ties.
From: Gut microbiome strain-sharing within isolated village social networks
The strain sharing rate was calculated for pairs of people who reported a reciprocated (n = 2,653) or non-reciprocated (n = 3,035) social tie as a non-kin/friendship relationship. The strain-sharing rate in non-kin reciprocated relationships is increased when compared to non-reciprocated ties in all types of relationships, except for Partner (Wilcoxon rank-sum test Close Friend P = 6.86 × 10−4, Partner P = 0.78, Personal or Private P = 2.68 × 10−14, Free time P = 2 × 10−17). Data are represented as boxplots where the middle line is the median and the lower and upper hinges correspond to the first and third quartiles; the whiskers extend from the hinge to the largest or smallest value, but no further than 1.5 * IQR from the hinge.
