Data were sourced from 108 Caucasian patients, 126 Caucasian controls, 55 Non-Caucasian patients and 159 Non-Caucasian controls. Actual numbers for each genotype are shown in Table 2. P: p-value. OR: odds ratio CI: 95% confidence intervals. Del: deletion. Ins: insertion. bp: base pair. Data were analyzed with contingency tables, χ-square, odds ratio and 95% confidence intervals.
