Comparison of the performance of the ECG criteria aMcNemar test comparing other ECG criteria versus Peguero-Lo Presti in patient with LVH in echocardiogram; bMcNemar test comparing other ECG criteria versus Peguero-Lo Presti in patient without LVH in the echocardiogram; a and b = p < 0.05 indicates lack of agreement.
CI confidence interval; NPV negative predictive value; PPV positive predictive value.
