Interestingly, in membranous nephropathy patients, the correlation between proteinuria and AT1R antibodies was very close to statistical significance, r = 0.42 (p = 0.08).Simultaneously, an inverse correlation between total protein serum level and AT1R antibodies, r =  − 0.42 (p = 0.07), was also very close to statistical significance. Here, AGTR1 is linked to membranous glomerulonephritis.
