Figure 1 Unadjusted cumulative survival of patients according to their baseline Kt/V at initial documentation of anuria. Continuous line represents patients with Kt/V above or equal to 1.67 (N = 90). Bold broken line represents patients with Kt/V below 1.67 (N = 60). The survival difference was statistically significant (P = 0.0269).

Figure 2 Unadjusted cumulative survival of patients according to their baseline Kt/V at initial documentation of anuria. Continuous line represents patients with Kt/V above or equal to 1.80 (N = 64). Bold broken line represents patients with Kt/V below 1.80 (N = 86). The survival rates were almost identical (P = 0.9786).

Figure 3 Unadjusted cumulative survival of female patients according to their baseline Kt/V at initial documentation of anuria. Continuous line represents patients with Kt/V above or equal to 1.67 (N = 68), and bold broken line represents patients with Kt/V below 1.67 (N = 22). The survival difference was statistically significant (P = 0.0024). It was not statistically significant when the Kt/V cut-off was made at 1.70 or above. The two survival curves become almost identical when Kt/V cut-off was made at 1.80.

Figure 4 Unadjusted cumulative survival of male patients according to their baseline Kt/V at initial documentation of anuria. Continuous line represents patients with Kt/V above or equal to 1.67 (N = 40), and bold broken line represents patients with Kt/V below 1.67 (N = 22). The survival difference was not statistically significant (P = 0.7098). It was not statistically significant at any Kt/V cut-off values. The two survival curves were almost identical when Kt/V cut-off was made at 1.70 (P = 0.8626).

Figure 5 Unadjusted cumulative survival of female patients according to their baseline Kt/V at initial documentation of anuria. Continuous line represents patients with Kt/V between 1.67 and 1.86 (N = 33), dashed line represents patients with Kt/V 1.87 or above (N = 35), and bold dotted line represents patients with Kt/V below 1.67 (N = 22). The survival difference was statistically significant (P = 0.0016). The difference between patients with Kt/V below 1.67 and those between 1.67 and 1.86 was significant (P = 0.004), and also between patients with Kt/V 1.67 and 1.86, and those 1.87 or above (P = 0.0285) Kidney International 2005 67, 2032-2038DOI: (10.1111/j.1523-1755.2005.00305.x) Copyright © 2005 International Society of Nephrology Terms and Conditions
