Abbreviations: CI, confidence interval; CM-SJS, cold medicine-related Stevens–Johnson syndrome; OR, odds ratio; SOC, severe ocular complication; SNP, single-nucleotide polymorphism; TEN, toxic epidermal necrolysis.
P value for allele or genotype frequency. Comparison was between patients and controls using the chi-square test (Pearson).
In table 1a, bold values denote P values that are significant after correction for the multiplicity of testing by the number of comparisons. In table 1b, bold value denotes OR with additive effect.
