Corrigendum to “A challenge for mutation specific risk stratification in long QT syndrome type 1” [J. Cardiol. 72(1) (2018) 56–65] (Journal of Cardiology (2018) 72(1) (56–65), (S0914508718300121), (10.1016/j.jjcc.2017.12.011))

The authors regret the errors in the sentence, tables and figures: Page 59, line 9, Statistical analysis The correct sentence is as follows: Categorical variables were compared using the χ² test or Fisher's exact test. In Table 1, there were several additional characters. The corrected Table 1 is as follows. Table 1 [Table presented] P: proband, F: family member, N.A.: not available, (−) at age of onset column: no event, (+) at genotype column: mutation positive, S.D.: sudden death, VF: ventricular fibrillation, TdP: torsade de points, (–) in Schwartz's score column: Schwartz's score was not calculated due to lack of clinical information. In Tables 2a and 2b, we have several mistakes in the numbers. The corrected Tables 2a and 2b are as follows. Table 2a [Table presented] C-loop: cytoplasmic-loop, TM: transmembrane region, VF: ventricular fibrillation, CA: cardiac arrest, TdP: torsade de points, NA: not available. Values were displayed by mean ± SD or n (%). Differences in characteristics were evaluated using one-way ANOVA or Kruskal–Wallis, χ2 or Fisher's exact test, as appropriate. Table 2b [Table presented] C-loop: cytoplasmic-loop, TM: transmembrane region, VF: ventricular fibrillation, CA: cardiac arrest, TdP: torsade de points, NA: not available. Values were displayed by mean ± SD or n (%). Differences in characteristics were evaluated using one-way ANOVA or Kruskal–Wallis, χ2 or Fisher's exact test, as appropriate. In Figure 2, the left side of F9, II-2 was filled with orange. [Figure presented] In Figure 5, right side of F26, III-6 and left side of F29, III-1 were blank. [Figure presented] In Figure 6A, the QTc intervals in V254M was corrected. In Figure 6E, the number of patients >16 y.o. in S277L was corrected. [Figure presented] The authors would like to apologise for any inconvenience caused.
