| IL-6 activity | −0.02 | 0.06 | [−0.15, 0.11] | −0.03 | 0.07 | [−0.16, 0.11] |
| Within neg. peer events | −0.09 | 0.29 | [−0.76, 0.44] | −0.05 | 0.25 | [−0.62, 0.38] |
| Between neg. peer events by IL-6 | 0.28 | 0.23 | [−0.13, 0.78] | 0.36 | 0.25 | [−0.08, 0.91] |

| Random effects | b | SE | 95% CrI (b) | b | SE | 95% CrI (b) |
| Intercept | 2.76 | 0.63 | [1.80, 4.26]a | 2.71 | 0.68 | [1.70, 4.35]a |
| Within neg. peer events | 0.41 | 0.25 | [0.03, 0.97]a | 0.19 | 0.16 | [0.01, 0.62]a |
Note. T = same time point. T+1 = next time point. “Between neg. peer events” = between-person component of number of negative peer events. “Within neg. peer events” = within-person component of number of negative peer events. IL-6 = IL-6 proinflammatory activity. CrI = Credible Interval.
Effect estimates and CrIs are presented as log-odds.
Credible Intervals that do not cross zero are considered significant effects.
