Childhood adversity and borderline personality disorder. Analyses complementing the meta-analysis by Porter et al. (2020).

A recent meta-analysis published in Acta Psychiatrica Scandinavica (1) investigated the association between reported childhood adversity (CA) and a diagnosis of borderline personality disorder (BPD). This meta-analysis is particularly instructive because it includes stratified analyses. The meta-analysis hereby demonstrates that both the type of control group and the type of primary studies play major roles for the effect-size estimation. However, we would like to provide complementary analyses to this important study. These complementary analyses aim at providing a more comprehensive and more accurate interpretation of the results reported in the meta-analysis.
