Limitations of Cockcroft-Gault and MDRD formulas in estimating GFR among top-level rugby players.

Conclusions: The MDRD formula underestimates the CrCl in rugby players, even when corrected for BSA. Conversely, the CG formula more closely approximates the actual CrCl measurement. The equations to estimate GFR should be used with caution in subjects having atypical anthropometric characteristics.
