Table 3.

Results of the GLMM including the following fixed factors: reproductive status (factorial variable: nulliparous = 0; pregnant = 1), social bond linking trigger and potential responder (factorial variable: strangers = 0; acquaintances = 1), time period (factorial variable coded as follow: 09:00am–12:30 pm = 1; 12:30–16:00 pm = 2; 16:00–19:30 pm = 3; 19:30–23:00 pm = 4). The coded identity of trigger and potential responder were entered as random factors

^a Not shown as not having a meaningful interpretation

^b Estimate ± SE refer to the difference of the response between the reported level of this categorical predictor and the reference category of the same predictor

^c These predictors were dummy coded, with Reproductive status (0), Bond (0), and Time period (1) being the reference categories
