Higher estimated net endogenous acid production with lower intake of fruits and vegetables based on a dietary survey is associated with the progression of chronic kidney disease

Table 3 Estimated change in mean eGFR from 2008

Year	Estimated change of mean eGFR (95%CI)		Difference (95%CI)
Year	NEAP < 50.1 (n = 50)	NEAP ≥50.1 (n = 45)		P
2011	−3.5 (−6.1, −1.0)	−6.1 (−8.8, − 3.4)	2.5 (−1.0, 6.1)	0.163
2014	−2.7 (−6.8, 1.4)	−8.5 (−12.8, −4.2)	5.9 (0.1, 11.6)	0.045
