To assess potential gender differences between the two groups, we performed a chi-square test (χ2 = 1.703, p = 0.192) and a multivariate logistic regression analysis (95% CI: 0.289–5.497, p = 0.758), both of which indicated no significant effect of gender on CF. We found that lower levels of insulin, triglycerides, albumin, retinol-binding protein, prealbumin, hemoglobin, and free triiodothyronine in the CF group. Here, TTR is linked to cystic fibrosis.
