Relationship between endogenous acid generation and renal acid excretion. Diamonds indicate data for the alkali diet and squares those for the acid diet. The equation for the straight line adopted to data by the least square method is y = 0.834 × + 27.09 (R2 = 0.362, n = 102, p < 0.01). The lines above and below the regression line are the 99% confidence limits.
