Mean weight and percentage weight decrease after 24 and 72 h between groups dissolved with 6 different solutions. Phys = physiologic sodium chloride solution, pH 7.0. Art = artificial urine, pH 5.7. EDTA = 0.03 M disodium EDTA+TEA, pH 8.5. R = renacidin, pH 4.0. S1 = citrate complex 1, pH 4.0. S2 = citrate complex 2, pH 3.9. ± s, ^aP < 0.01 vs R, S1 and S2.^bP < 0.05 vs S1, S2.^cP < 0.05 vs S1. n = 18 for each group. For statistics, see results section.
