In article “Significant treatment effect of adjunct music therapy to standard treatment on the positive, negative, and mood symptoms of schizophrenic patients: a meta-analysis ”, some values of Hedges’ g in main results of the meta-analysis might mislead the readers’ interpretation of our results. Different values of Hedges’ g may derive from different methods of standardization when using Comprehensive Meta-analysis software. The main results of significance in current study remained significant. By using different method of standardization, we found that the main treatment effect of adjunct music therapy in schizophrenia was significantly larger than those without adjunct music therapy (Hedges’ g = 0.596, 95 % CI = 0.350-0.842, p < 0.001). At the same time, the treatment effect of adjunct music therapy in schizophrenia remained significantly larger than those without adjunct music therapy in scores of positive symptoms, negative symptoms, and mood symptoms (Hedges’ g = 0.483, 95 % CI = 0.053-0.913, p = 0.028; Hedges’ g = 0.673, 95 % CI = 0.385-0.961, p < 0.001; Hedges’ g = 0.677, 95 % CI = 0.434-0.919, p < 0.001, separately).
