Comparison of the study population split into three groups. (A): age; (B): serum creatinine; (C): eGFR; (D): blood urea levels. Group 1: kidney histological correlated to IRD known at the time of biopsy. Group 2: kidney histological findings not correlated to IRD known at the time of biopsy. Group 3: “de novo” IRD not present in medical history at the time of biopsy. *** p < 0.001. IRD: immuno-rheumatological disease. eGFR: estimated glomerular filtration rate. circles and asterisks are outliers.
