Among participants, from the first to fourth quartile of QTc interval, the proportion of patients with DPN appreciably increased and the nerve conduction velocity obviously decreased (\n                      <jats:italic>P<\/jats:italic>\n                      for trend &lt;0.001). The univariate and multivariate analyses showed that prolonged QTc interval was closely associated with increased risk of DPN (univariable odds ratio 1.112, 95% confidence interval 1.097\u20131.127,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001; multivariable odds ratio 1.118, 95% confidence interval 1.099\u20131.137,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001). Receiver operating characteristic analysis for the diagnosis of DPN showed a greater area under the curve for QTc interval of 0.894 than the median nerve motor conduction velocity of 0.691, median nerve sensory conduction velocity of 0.664 and peroneal nerve motor conduction velocity of 0.692. The optimal cut\u2010off point of QTc interval for DPN was 428.5\u2009ms with sensitivity of 0.715 and specificity of 0.920 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001).
