a
Corresponds to n out of total responses.
b
Corresponds to percentage out of total responses.
c
Based on suicidal ideation intensity ratings for only those observations in which suicidal ideation was present (scale = 1–11).
d
Corresponds to each participant’s average across observations.
e
Corresponds to the subset of the sample that reported presence of suicidal ideation on at least one EMA survey.
Note. Proinflammatory values are in pg/mL.
