Similarly, total T3 levels showed a decreasing trend in the high-risk group (103.365 ng/dL vs. 111.095 ng/dL), with this difference also being statistically significant (p < 0.001).

The borderline significance observed for T3 (p = 0.052) suggests that the association may become clearer with a larger sample size or more targeted data.
After adjusting for age, BMI, and PSA levels as continuous variables, the association between FT3 and prostate cancer risk remained positive but did not reach statistical significance (HR = 1.496, 95% CI: 0.868–2.580, p = 0.147) (Table 2 ).
Across T3 quartiles, except for the highest, risk was lower compared to the reference quartile (Q1), with an overall trend of decreasing PCa risk with increasing T3 levels (p for trend = 0.023).This trend remained statistically significant in Model 1 and was maintained in Model 2, although the p for trend increased to 0.084.
