Correlation of the number of CD4⁺CD25^high Treg cells and lymphocytes with renal function parameters.

Parameter	Number of CD4+CD25high Treg cells	Interpretation	Number of lymphocytes	Interpretation
Creatinine	ρ = −0.45 P = 0.002	Low negative correlation	ρ = −0.52 P < 0.001	Moderate negative correlation
eGFR	ρ = −0.44 P = 0.002	Low positive correlation	ρ = −0.53 P < 0.001	Moderate positive correlation
BUN	ρ = −0.28 P = 0.05	Trivial	ρ = −0.002 P = 0.99	Trivial

eGFR: estimated glomerular filtration rate; BUN: blood urea nitrogen; ρ: Spearman's rank correlation coefficient or Spearman's rho.
