Among active LN patients, baseline urinary NGAL levels were significantly lower among those with complete response (median 10.86 ng/mL, IQR 6.16 to 22.4) than among those with partial response (median 19.91 ng/mL, IQR 9.05 to 41.91), and nonresponse (median 65.5 ng/mL, IQR 18.3 to 103) (P = 0.006) (Fig. 1a). The gene discussed is LCN2; the disease is lobular neoplasia.
