1Predicted probability of discontinuation of dialysis from LS-means estimates from the logistic regression (i.e. estimated at average values of all covariates included in the model);
2The odds of dialysis discontinuation for a ESRD network relative to reference network 9;
*Reference, network 9 with the rate of dialysis discontinuation closest to the median of estimated probability for the overall study population;
ESRD = End-Stage Renal Disease; CI = confidence interval.
