GLMM analysis for repeated measures of serum albumin between IgAN-NS and IgAN-NR without CR.

	F-value	p
(Intercept)	11502.8	<.001
Cohorts	39.1	<.001
Follow-up time	62.5	<.001
Cohorts:Follow-up time	1.7	.09

The GLMM was utilized to assess the impact of repeated measures on various factors between the two cohorts and across multiple follow-up periods. The statistical differences were assessed using ANOVA, which enabled the identification of both intergroup/intragroup variations. The cohorts included the IgAN-NS (IgAN with NS) and the IgAN-NR (IgAN with nephrotic-range proteinuria). The interaction between cohorts and follow-up periods was denoted as Cohorts * Follow-up duration. Additionally, CR represented complete remission of proteinuria.
