 * Number of parameters shown in table 3 that are within the range recommended by K/DOQI. See methods section for individual ranges. Each row shows the proportion of patients within each category achieving the indicated number of parameters at goal. The last row shows the mean number of parameters at goal within each category. Pvalues were determined by ANOVA with Welch's correction for unequal variances followed by Tamhane's post hoc pairwise comparison of SNC and LNC within each Stage of CKD. ^{#} Stage 4 = GFR 15–29, Stage 5 = GFR <15 ml/min/1.73 m^{2}. The glomerular filtration rate was estimated using the modified MDRD formula [1]. ^{†} SNC: seen for 6 months or less, LNC: seen for more than 6 months
