LN class conversion in up to four kidney biopsies
Count plot illustrating the percentage of biopsies with each LN class at biopsy 1–4 (bx1–4). The area of the circle is scaled within each biopsy episode within each plot. Almost all possible class switches were observed at any time point. Proliferative LN was defined as ISN/RPS class III or IV ± V. Membranous LN was defined as pure ISN/RPS class V.
