LN	28.6 ± 4.0	−4.8 ± 0.9	−10.7 ± 0.8	0.89
HK-Control	30.1 ± 3.5	−10.3 ± 2.7	−13.9 ± 2.6	1.61

This table summarizes data presented in Figs 2 and 7. J_K/PD_te is the slope of the regression line between J_K and PD_te. NS, non-significant regression. Values are means ± SEM, number of animals as indicated in figure legends. PN, PAN-induced nephrotic rats; LN, Na⁺-depleted rats; HK, K⁺-loaded rats.
