Similarly, RPIA [OR (95% CI): 0.317 (0.170−0.589), p = 2.84 × 10−4] was also protective, whereas PDIA5 [OR (95% CI): 1.328 (1.130−1.561), p = 5.88 × 10−4] and IL31 [OR (95% CI): 1.906 (1.254−2.896), p = 0.003] were risk factors for myocarditis (Figure 5). This evidence concerns the gene IL31 and myocarditis.
