Table 4.

CTLA4 promoter haplotypes present in springer spaniels. Number of each haplotype is shown (with frequency in brackets) for cases, 2n = 56, and controls, 2n = 114. NaN: not a number; OR: odds ratio; 95% CI: 95% confidence intervals of the OR. p values for individual 2 × 2 tables are given with significant results coloured red, overall significance p = 0.291
