  • a Results are expressed as n (%) or mean ± SD (10th to 90th percentiles). iGFR, 125I-iothalamate GFR; eGFRMDRD, estimated GFR with the Modification of Diet in Renal Disease formula; eGFRCG, estimated GFR with the Cockcroft-Gault formula.

  • b P = 0.004 versus nondiabetics.

  • c P = 0.01 versus nondiabetics.
