In agreement with the negative association between age and FT3 levels, the low-FT3 group was 15 years older on average (p=0.007) and presented a higher incidence of diabetes (p=0.045), hypertension (p=0.017) and cardiopathy (p=0.004), lower hemoglobin (p=0.046) and lymphocyte count (p=0.006), as well as a higher neutrophil-to-lymphocyte ratio (p=0.037) and C-reactive protein levels (p=0.013). This evidence concerns the gene CRP and Hypertension.
