Dot Plot showing TREC copies/μL blood (A) and TREC copies/10⁶ cells (B) among the study age groups. Blue full circles represent healthy males and red empty circles represent healthy females. A significant inverse correlation was observed between TREC levels and both pediatric and adult age groups (Pediatric: r = −0.6488, p < 0.0001 for copies/μL and r = −0.5487, p < 0.0001 for copies/10⁶ cells; Adult: r = −0.4924, p < 0.0001 for copies/μL and r = −0.6289, p < 0.0001 for copies/10⁶ cells).
