Meta-analysis showed that the prevalence of QTc prolongation in patients with schizophrenia taking antipsychotics was about 4.0% (95% confidence interval (CI): 3.0%\u20135.0%, p\u2009&lt;\u20090.001). The prevalence was about 4.0% in Asia (95%CI: 3.0%\u20136.0%, p\u2009&lt;\u20090.001), about 5.0% in Europe (95%CI: 2.0%\u20137.0%, p\u2009&lt;\u20090.001), and about 2.0% in America (95%CI: 1.0%\u20133.0%, p\u2009&lt;\u20090.001). Sensitivity analyses indicated the robustness of the result. Publication bias analysis reported a certain publication bias ( t\u2009=\u20093.37, p\u2009=\u20090.012). Meta-regression suggested that female and elderly patients were clinically associated with a higher prevalence of QTc prolongation. According to included studies, smoking, comorbidity of cardiovascular disease, and abnormal levels of high-density lipoprotein\/low-density lipoprotein might be related to QTc prolongation in patients with schizophrenia taking antipsychotics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The prevalence of QTc prolongation in patients with schizophrenia taking antipsychotics was about 4.0%.
