Tobacco use disorder is associated with increased risk of cardiomyopathy in a population-based study from Taiwan.

This difference did not reach statistical significance after Bonferroni correction (α = 0.0167) . 1–5 years : AOR = 1.592 (95% CI = 1.270–1.789; p < 0.001), statistically significant after correction. > 5 years : AOR = 2.743 (95% CI = 1.625–3.891; p < 0.001), statistically significant after correction.

These findings indicate that prolonged TUD exposure (> 1 year) was associated with higher odds of cardiomyopathy, whereas shorter exposure (< 1 year) showed only a nonsignificant trend after adjustment for multiple comparisons.
