Based on the Kolmogorov-Smirnov’s test for normal distribution, %Female was determined as normally distributed, therefore the means (SD) are presented and the values from the F-test for statistically significant difference are reported
The Standardized Transplant Ratio was calculated by the University of Michigan Kidney Epidemiology and Cost Center and was included in the 2008–2011 Dialysis Facility Report. The ratio was calculated by dividing the number of expected transplant by the number of observed transplants, and then standardized against the national average.
