Figure 2. Relation between ePTFp, FGF23, and renal tubular damage.

Figure 2

See the text. (A) The experimental design. Uninephrectomy was performed to reduce the nephron number to one-half. (B) The double logarithmic plots between ePTFp and relative mRNA levels of osteopontin in the kidney (upper panel) and between ePTFp and serum FGF23 levels (lower panel) fitted with two-segmented linear regression with the slope of the first segment being zero. The threshold values of ePTFp and FGF23 were indicated. Modified from [12].
