  1. In column one, data given as the number (% of total) or mean ± one standard deviation of patients with polycystic kidney disease who had the disease or factor. In column two, data are for all other ESRD patients. Odds ratios are the strength of the association of a disease or factor with polycystic kidney disease, with 1.0 being neutral. * = p < 0.01 vs. patients with all other causes of ESRD by Chi Square Test Ap < 0.01 vs. patients with all other causes of ESRD by Student's t-test Bcontrolled for all covariates listed in methods section. Only results with statistical significance (p < 0.01) are shown.
