Four renal pathologists independently scored the AI and CI on 84 renal biopsy specimens from patients with lupus DPGN followed for 109 +/- 74 weeks (mean +/- SD), and the mean score was compared to the development of renal failure and to adverse outcome (combined data for renal failure, death and predefined clinical stop points). Receiver operator characteristic curves were derived from a series of 2 x 2 tables in which one variable was renal failure or adverse outcome and the other variable was AI or CI dichotomized by a cut-off point. Over the entire range (0 to 10) of the CI there was no value that separated patients who developed renal failure from those who did not. The ROC curve analysis indicated that the sensitivity and specificity of the CI were too low to allow it to function as a good test. Once patients entering renal failure were identified, the mean CI approached but did not reach a significant difference when compared to the mean CI of those who did not go into renal failure (4.38 +/- 0.42, mean +/- SE vs. 3.19 +/- 0.23, P = 0.0620). The CI did not predict the adverse clinical outcomes. There was no cut-off value of the CI which separated patients who had an adverse outcome from those who did not, and this result was confirmed by ROC analysis.(ABSTRACT TRUNCATED AT 250 WORDS)}, author = {Schwartz, M.
