They found that the prevalence of estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m2 in this population rose from 40.5% in 1988–1994 to 49.9% in 1999–2004 and 51.2% in 2005–2010.

The prevalence of a more severe reduction in eGFR (less than 45 mL/min/1.73 m2) rose from 14.3% in 1988–1994 to 18.6% in 1999–2004 and 21.7% in 2005–2010.
