N = 52, n_{recurrent events} = 6,767, mean recurrent laughing events per subject = 130.1. Reference for gender was men. Reference for Time of Day were the night hours 1 a.m.–9 a.m.; ^***p < 0.001, ^**p < 0.01, and ^*p < 0.05. cgm, Centered around the grand mean. As B represents log odds ratios, effects can be interpreted as small (0.36), medium (0.90), and large (1.45; Sánchez-Meca et al., 2003).
