Fig. 1From: Long-term changes in renal function after treatment initiation and the importance of early diagnosis in maintaining renal function among IgG4-related tubulointerstitial nephritis patients in JapanMean differences (95% CI) of eGFR between the baseline and each time point were estimated by linear mixed models. Mean values of eGFR between the baseline and each time point were significantly different, which meant that eGFR at each time point was significantly higher compared to that at the baseline. We especially found large changes in eGFR from the baseline to 2 and 6 months after treatment initiation. The mean differences of eGFR between the baseline and from 6 to 60 were relatively stable.
