EGFR and chronic kidney disease: A very-LPD featuring NFA demonstrated a significantly higher EGFR (MD, 1.00; 95% CI, 0.35–1.64, p = 0.002) with low heterogeneity (I2 = 34%), as well as a lower SCL (MD, −0.44; 95% CI, −0.75 to −0.13, p = 0.006) with moderate heterogeneity (I2 = 52%), a reduced BUN (MD, −35.34; 95% CI, −64.27 to −6.42, p = 0.02) showing high heterogeneity (I2 = 99%), and lower PH levels (MD, −1.25; 95% CI, −2.33 to 0.18, p = 0.02), also with high heterogeneity (I2 = 96%), in contrast to the typical LPD among individuals with CKD, as illustrated in Figure 2, Figure 3, Figure 4 and Figure 5.
