Proteinuria and survival measurements. (a) Survival and (b) proteinuria were measured weekly starting at 29 weeks of age (n = 10). Grade 0.5 proteinuria = 'trace'; grade 1 = about 30 mg/dL; grade 2 = about 100 mg/dL; grade 3 = about 300 mg/dL, a clinically significant level; grade 4 = more than 2000 mg/dL; grade 5 = death.
