Erratum to: Combined Neurofeedback and Heart Rate Variability Training for Individuals with Symptoms of Anxiety and Depression: A Retrospective Study

The original published version of this manuscript included a typo on page 43, in the ‘Statistical Analysis’ subsection of the Methods. The original text read: “All p -values were assessed using an experiment-wise error rate of α = 0.05 adjusted for multiple testing and comparisons with Bonferroni correction.  With 19 comparisons, the Bonferroni corrected significance level was  α B  = 0 .” The “ 0 ” was a typographical error.  The Bonferroni corrected significance level for the study is 0.05/19,  α B = 0.0026 , and the Methods section text has now been corrected to reflect this. The text now reads: “All p -values were assessed using an experiment-wise error rate of α = 0.05 adjusted for multiple testing and comparisons with Bonferroni correction.  With 19 comparisons, the Bonferroni corrected significance level was  α B  = 0.0026 .” The authors regret any confusion that this error may have caused.
