From: Effect of urine pH changed by dietary intervention on uric acid clearance mechanism of pH-dependent excretion of urinary uric acid

Figure 2

Relationship between excreted uric acid as expressed in mg uric acid in urine per day and urine pH. In A. Diamonds indicate data for the alkaline diet and squares those for the acidic diet. The equation for the straight line obtained by the least square method is y = 118.9x-335.8 (r2 = 0.2098, n = 57, p < 0.01). In B. Corrected relationship between excreted uric acid as expressed in mg uric acid in urine per day and urine pH. Given the loading difference of purine bodies, data for uric acid excreted in alkaline urine were multiplied by correction factors, as described in the text. The equation for the straight line obtained by the least square method is y = 332.25x-1525.6 (r2 = 0.5406, n = 57, p < 0.01).
