Erratum: Alcohol-related risk of suicidal ideation, suicide attempt, and completed suicide: A meta-analysis (PLoS ONE (2015) 10:5 (e0126870) DOI: 10.1371/journal.pone.0126870)

Abstract

After publication of this article [1], concerns were raised about the inclusion of the study by Rossow and Amundsen [2] in the analysis shown in Fig 3, as this study reported estimates of the association between alcohol use disorder (AUD) and completed suicides but did not report on the association between AUD and suicide attempts. The authors apologize for this error and present here an updated version of Fig 3 in which this study is excluded. In the updated analysis, the summary measure of the effect of AUD on suicide attempt was 2.79 (95% CI: 2.16, 3.43), compared to 3.13 (95% CI: 2.45, 3.81) in the original analysis [1]. However, the association between AUD and suicide attempt remained significant and strong (P<0.001). The heterogeneity across included studies, based on I2 statistics, reduced from 88.5% in [1] to 86.3% in the reanalysis. The funnel plot analysis for attempted suicide (Fig 6) was also corrected accordingly, excluding the Rossow 1995 article from the analysis. Please see the updated Figs 3 and 6 here.
