Note. k = number of samples. CI = confidence interval. ET = Egger’s Regression Intercept test, 2-tailed p-value is reported; significance indicates potential publication biases. Trim&Fill = Duval’s Trim & Fill test, random effects estimates, Q-values, and the number of studies trimmed are reported. See H3 and H7 in the Meta-Analytic Approach Section.
TB = thwarted belongingness. PB = perceived burdensomeness. CS = capability for suicide. Attempt C = attempt history measured continuously. Attempt D = attempts measured dichotomously (i.e., yes/no). Attempt C/D = attempt history; analyses predicting attempts measured continuously and dichotomously were collapsed. Risk = suicidal ideation and behavior.
