Table S1. Baseline clinical and laboratory data and UAGT levels of iMN patients, MCD patients, and normal subjects. Table S2. Pearson’s correlation of UAGT and other variables in the iMN or MCD patients. Table S3. Multivariate linear regression analysis between UAGT and other variables in iMN patients. Figure S1. Comparison of the UAGT levels among the iMN patients, MCD patients and normal healthy subjects. Both of the iMN patients and MCD patients had higher UAGT levels than normal subjects; there were no differences between the iMN patients and MCD patients. Figure S2. Correlations between UAGT and other variables in iMN patients: A), UAGT levels were negatively correlated with eGFR (r = − 0.352, p = 0.014); B), UAGT levels were negatively correlated with serum albumin (r = − 0.393, p = 0.006); C), UAGT levels were positively correlated with proteinuria (r = 0.614, p
