IgAN, immunoglobulin A nephropathy; AS, activity index score; CS, chronicity index score; TS, total score. The intensity of deposits detected by immunofluorescent microscopy was graded semi-quantitatively on a scale from 0 to 4: Negative, 0; minimal in intensity, 0.5; slight in intensity, 1; moderate in intensity, 2; marked in intensity, 3; and marked in intensity and extent, 4.
